Logitech - G604 LIGHTSPEED Wireless Optical Gaming Mouse with 25000 DPI HERO sensor - Black

This is a new addition to the growing list of Logitech G products geared towards Esports and gaming in general. While this mouse doesn't look particularly out of the ordinary, which is good, has some unique capabilities not only for gaming but also for regular desktop use. Unlike the Logitech professional line, these use their own software (G Hub) and wireless receiver that is not compatible with Logitech's traditional 'Unifying' receivers. Design and controls: While not specifically designed as an ergonomic mouse, it feels comfortable to hold. Particularly, the thumb rest on the left is good. The palm rests in a natural position. The scroll wheel has a selectable modes (with a button behind it): Free wheeling and sequential. The difference is that in the fist mode, the wheel which feels like a solid metal, scrolls freely, without inertia. In the other mode, it 'clicks' while scrolling. The scroll wheel can be clicked for a 'middle button' and has left and right movements. Then there is a set of buttons at the index finger, which are by default set for DPI settings, and are configurable. At the thumb, there is a set of 6 buttons (3 in two rows), which are customizable through the G software. These can be reached with the thumb after a short practice. Tracking: Like other gaming mouse from Logitech, it uses the 'HERO' sensor with up to 16K DPI. The mouse has gliders in its four corners and center. As expected, it works on every surface I tried. Connectivity: It connects via either an USB receiver, which is dedicated to the mouse and cannot be shared with other G devices, which is the recommended way with 1ms lag (as stated by Logitech), or via Bluetooth (which would have higher lag). The proprietary wireless connection is also more battery efficient than standard Bluetooth. The mouse can connect to two devices, and switch between the USB adapter and Bluetooth by pressing a button in the middle of the mouse. Opening the rear of the mouse, next to where the AA battery goes, there is storage for the USB adapter. There is no way to use the mouse with an USB cable. It requires an AA battery (Alkaline, not rechargeable), which should last months to a year. The mouse comes with an USB extension cable, so if using a desktop PC, the wireless adapter can be closer to the mouse. Software: Logitech's G hub works across all its G line of products (I'm using it with the G613 wireless gaming mechanical keyboard). Upon installing the software, it upgraded the firmware on the mouse., and then walks you the buttons assignments. The software works on PC and Mac. I tested it on macOS 10.4.6 (Mojave) and works fine, like in Windows. The buttons assignments can be programmed per profile, and the profile can switch based on the running application/game. The mouse can also optionally store up to 5 profiles in its own memory. Also the G Hub can switch between standard macros and 'G-Shift' mode (via a macro on the mouse or keyboard) adds another layer of button assignments. Profiles can be shared (Internet) via the G Hub software, directly, which works like a forum/profile store (Free). There are no lights on the mouse, except for a pairing/status light in the center that usually remains off. Overall: Excellent gaming mouse. I'd prefer rechargeable batteries, but being able to replace the battery using standard alkaline AA eliminates the issues associated with Lithium. Purpose-built wireless interface works as well as wired, with greater convenience and no wires to tangle on. Buttons are easily configurable through G Hub. The mouse feels great to hold and right-sized for 'medium' hands. Right-hand only design. A drawback of the proprietary 'lightspeed' wireless adapter is that it's one per device, even multiple G devices on the same computer require one adapter for the mouse and one for the keyboard. In exchange, it's faster than other wireless technologies, and I can attest that the G keyboard has been on the same pair of AA batteries for over a year with very little drain, and should keep going for at least another year.

I’m a fan of Logitech products, some better than other but have always preferred their mice, so I have plenty for comparison. Unboxing: This new G604 comes like all the other Logitech mice lately, well packaged in a nice black Logitech logoed box. Inside is the mouse, single AA battery, manual all neat and ready to set up. The wireless dongle is under the battery door at the rear. Setting up: The first thing you do is open the back of the mouse up, there’s a small cover that opens up on the top back ¼ of the mouse, it’s held on by magnets and comes off very easily. There a compartment for a single AA battery and the wireless receiver is also stored here, nice for travel. I simply took out the wireless dongle, inserted it in an open USB port “fortunately my monitor has 4 USB ports”, plugged it in and inserted the battery, replacing the back cover. The AA battery is suppose to last around a month using the dongle, and I'll be happy with that if that's the case. Getting a month off a single AA is pretty amazing, but will see how it does in real use. I already had the G Hub software installed and it picked up the new mouse right away. There you can set the DPI sensitivity, and program all the buttons for pretty much anything you want. It also has a custom macro section for setting up your macros. After setting up all the buttons the way I liked “never had one with so many buttons” it I was off to using it. Actual use: Logitech really did a great job on this new mouse and it’s going to be my favorite one for sure. Even though I have smaller hands I prefer a heavier larger mouse, small ones just feel too cramped. This one being on the heavier side is perfect, I really don’t like light mice. There’s a button right below the scroll wheel for scroll lock so you can have smooth or notched scrolling of the wheel. Then there’s an additional button right below that for turning on Bluetooth and setting it up. I really have no need for that now so I’ll be using it with the wireless dongle. I’ve been trying this out for everyday use and for playing some Skyrim, Witcher 3 and Fallout 4. And I can say this mouse is accurate, smooth and just feels great in my hand. The other mice are going to get lonely sitting on the shelf as I can’t see myself going back to any of the, even if some have the fancy lighting “which doesn’t do anything for me”. I also have a Logitech Pro wireless “which costs more” but I really don’t care for the feel as it’s made as an ambidextrous mouse, so if you are left handed I wouldn’t consider the G604, all the buttons on the left would just get in the way and it’s not shaped for lefties. Conclusion: This is going to be my favorite mouse, hands down. It fits me perfectly, the programmable buttons are great. The left side buttons may be a little too far forward for me to use the front two of the six comfortably but I still have 4 that I can easily use and setting up some macros for Skyrim worked out great. If you like a lighter mouse then this may not be for you, it will be a personal preference but this one is definitely not on the light side. It’s also pretty large too so again; it’s all going to be personal preference. In the end though this is really a great mouse for gaming and just regular computer use and the added thumb rest on the left make it that much more comfortable and stable.

This is a strange mouse. I like Logitech mice. I have been using Logitech mice for decades. This... is a strange mouse. For starters, it has legs, risers that keep it elevated. I'm not sure what this accomplishes. This is also the first mouse I have had in a while that seems to need to be broken in. I use a hard mouse pad, and the Logitech G604 feels like it is constantly scraping against the mouse pad. Instead of a smooth glide, I get a small bit of resistance. It's gotten better (the gliders on the mice seem to be wearing and the experience is gradually smoothing out), but it's nowhere near as smooth as my other mice at the moment. Even on a cloth mouse pad, the G604 isn't as smooth as my other Logitech and Corsair mice. The ergonomics are taking me a bit of time to get used to. It feels like someone saw the ship "Serenity" from the show "Firefly" and said "design a mouse shaped like that!" The back looks like a bird's beak. The more I use it, the more I like it, but the G604 has taken me a bit to get used to. I feel like I am gripping it more than I do other mice. My palm doesn't rest quite as easily. Time will tell how ergonomic this mouse really is, but for the moment I am adjusting. The 1MS response time is great. In my experience, it is near indistinguishable from wired mice. However, don't expect to get that same response time over Bluetooth. Switching between bluetooth and Light-speed Wireless Sensor has been easy enough. It's nice having a mouse that can work on my PC one second and then my Samsung Tablet or my Laptop with a button press. For the most part, the buttons have been responsive. I like how snappy the primary and secondary buttons are. The six thumb buttons are a bit cumbersome, but I am getting used to it. They're a bit mushy, but they work and it's nice having the hotkeys there for office or gaming applications. The DPI switches work easily and the scroll wheel is a bit loud during ratcheted scrolling, but it works well. There is no weight adjustment. I can't say the mouse feels too heavy or too light. But, I know some purists want that level of customization, and the G604 doesn't offer that. Also, should probably point out that this mouse is probably best suited to right handed users. Lefties will be a bit out of luck. GHUB is simple enough and it's highly recommended that you download GHUB to get the full experience. I've never had problems with GHUB itself, however, I have had some conflicts between GHUB and Corsair's iCue in the past. So, in conclusion, this is a strange mouse. It's a mouse with a great response time and the thumb buttons can be easily customized, but the ergonomics and the less than smooth glide, make it hard to call "great". I'm confident it will get smoother as I use it, but this design just doesn't feel as polished as I have come to expect from Logitech.

Originall I was planning to get the MX Master for coding/productivity. But then I stumbled upon this find and found it to be on sale as well. In my opinion, this is better than MX Master (at-least for the Mac users) since it has a lot of programmable buttons, so I can program them all for the Mac gestures. I've read reviews of G Hub being so bad, I am not a professional gamer so my review probably doesn't matter much on that front but I have found G Hub to be awesome at-least on Mac. Another reason you shouldn't go for the MX Master is due to the higher DPI on this one. Also this is future proof for my gaming endeavors.

The Logitech G604 "LIGHTSPEED" wireless mouse is a great addition to my gaming setup. There’s a stigma that surrounds wireless gaming mice and responsiveness, but I don’t feel the impact with the G604. As this isn’t a wired mouse, it has to have a battery; the bonus here is that it’s a replaceable battery. I’ve been all about rechargeable mice for a long time, but since the G604 is geared towards gaming, it makes sense to be able to replace the battery with minimal downtime / waiting to respawn. Removal of the back cover is simple and there’s a small groove to guide you to where you have to lift. To get the customizations, you have to use the G Hub software, but it’s a no-go for the Mac; Logitech support still hasn’t responded to my inquires about the issues getting it running. On the PC, however, as soon as it saw the mouse, G Hub *knew* that a firmware update was available and once given approval, pushed it to the mouse within a few minutes. Keeping it close (I went with the USB dongle) made sure that there were no interruptions or partial-updates. I really used the mouse for Borderlands 3. Immediately, I found that super responsive DPI-switching gives me the ability to hop to 3200 DPI quickly scan to acquire a target with minimal mouse movement and then pop to a lower DPI for a less responsive set of combat firing. I didn’t try a DPI of 16K, but the thought of how little you have to do to get the cursor from side to side is comedic. The scroll release has a nice click and it’s delay free. Unlike some of the Logitech mice, it doesn’t appear to be electronics driven (read: MX Master 2S) as it needs a noticeable push to move it from free-flow to click. The scroll wheel is also a panning wheel, as it allows left/right/down clicks to boot. The traditional left/right buttons have a nice click and repetitive clicking can generate some serious noise, whereas other home/office mice won’t be so noticeable. Six thumb buttons allow for a seemingly endless amount of customizations. The G Hub software allows you to save different profiles so remapping doesn’t have to become part of your pre-game warm-up. Then, you have +/- on the side of the left-mouse button, which by default controls your DPI switcher. I mean seriously -- I like to game, but 16 buttons takes some muscle memory that I just don’t have time to get into. Pairing this with the Logitech G Pro keyboard was a great choice, though this mouse doesn’t share the G Pro keyboard’s RGB capabilities. Given that, it seems like they really focused on quality and didn’t add features (RGB) that could be lag-inducing. One thing I’ve noticed - is there are no weights that can be used to make it heavier, as it is pretty light. I would have liked to see that as part of the mouse, as not everyone likes the lighter mice -- and would rather slow it down a bit on purpose. In this review period, I didn’t need Logitech support - again, because I’m still waiting on a response from my keyboard. So, for me and my gaming needs, this is a 5-star mouse!

Good mouse, I use it with my gaming laptop. It didn’t had any delay, just a little when the bluethoot usb was too far away, but it comes with a cable to extend the range.

Pros: - 6 side buttons, and the two buttons on the left click are all remappable with the GHub software, and if you assign gshift to one button, you can map another 7 buttons - Battery life is great, ghub shows full battery after heavy use for 3 weeks with the mouse on the whole time - Free scroll is amazing - Bluetooth option if you don't want to use a dongle Cons: - Personally didn't like the mouse clicking noise when not in free scroll, find it a little too loud - Sometimes I like to use the mouse on a blanket or whatever surface I can find, and when I do, the mouse becomes jittery and randomly moves around (my old mouse didn't do this, logitech m510)

So far my favorite logitech mouse! No lag Great precision for gaming man and its also bluetooth i can use on my ipad win win
