Easy to hook up works great for gaming. Would buy again.

amazing for laptop love the lighting on it very easy to use

Response is amazing and a big package in a small and portable size. Love taking this with me to school with my laptop and casually playing games on the side.

Im a coder not a gamer. I got this mouse because I assumed gamers have the best equipment. Plus...I like the lights. So far the mouse does what I need. Only time will tell. Feels good, quick response. I’m not entirely fond of the wireless function. It’s not that great. Kinda choppy. when it’s plugged in it’s fine.

Extremely comfortable and perfect for gaming! The only problem I've noticed is that there seems to be a SLIGHT delay when I move my mouse after not using it for a couple of minutes. I'm not sure what the problem is, but I don't knock the mouse. It's probably something to do with my PC, but other than that, it's great!

This mouse is great on a PC or Mac, but the Bluetooth mode does not work on iPad. Wired, it will work if you have an adapter but there is no way to get it to work at this time using the Bluetooth. If buying this for iPad is your goal, DO NOT GET IT. If you are just looking for a mouse you can switch between 3 devices with ease (Wired, Bluetooth, & dongle) This mouse is awesome! 5 stars for sure. But for my uses, in particular the iPad, this mouse is almost useless. If Corsair ever updates this product to work with iPadOS using HID (The protocol Apple uses for iPadOS) this is an easy 5 stars. Review written using iPadOS 14.4.1

This mouse is super responsive and is easy to charge.

Great quality product. Would definitely recommend

Good ptice and good product. Bought for sons games

Matches well with my Corsair K95 keyboard and the iCue soft ware. It charges by way of an included USB cable, I would've preferred AA or AAA batteries. I haven't gamed with it yet. I prefer wired mice and keyboards. I bought this mouse to clean up my desktop.

Excellent wireless mouse with little to no latency.

Great mouse... just don't lose the charging cable lol. It's a USB-C-to-USB-A cable, but has a proprietary plastic mold on the USB-C end that plugs into the mouse to charge it, so third-party cables probably won't work.

Where do I even start, it put it blunt, the quality of this mouse has put me off ever buying another corsair product, my first mouse (I'm now i'm my 3rd replacement and have fully given up) was shipped to me on the 15th of May, by the middle of June it already had double clicks so bad that on click tests I was getting 70% double click on my left switch. I'm a pretty calm person, I contacted support, let them know my problem, and was happy to wait. I get my mouse, after having paid them in advance to get it faster, it's "certified refurbished" the wireless dongle is disgusting (thanks for that by the way, not like we're in the middle of a massive world wide plague where being clean is important), filled with random crumbs and dust, the middle scroll wheel is barely in place as if they didn't even connect it, each switch when click has a deep metallic ping noise, there's connection issues and it constant randomly turns off. Again, I'm a calm person, I contact them back to let them know that they basically sent me a dead mouse that they found on the side of the road, they apologize and don't know what happen after a week and a half waiting for their response they say they'll send out a new mouse that wont be refurbished as obviously they cant' be trusted to repair their own products. A week passes, I get my mouse, it's refurbished again, wonderful, I'm now on mouse three, all the switches have heavy ping noises but I didn't get double clicks instantly. I close my ticket. One week passes with insanely light usage as I've basically gone back to my G403 when I don't need wireless, I'm already getting double clicks, this time on both left and right switches. It's 2020, I can buy replacement high quality switches for mice for $1.50 retail that will never double click, if I was a massive company buying thousands of them I'd get them for way less, there's no excuse for the low build quality at this price point, I've had no name mice from amazing that have lasted me 5+ years and only died because the batteries in them failed at a third the price. Corsair is leaning way too much on their brand name these days instead of the actual quality of their products, pick a different brand.

Excelent!!! .........................................

I love this mouse more than any I’ve had before. 10/10 recommend for anyone who is looking for an excellent gaming mouse. My whole family uses it for our PC and love it!

I bought for my godson and it worked excellent!!!!

Ordered this mouse for my new PC and have had no issues with it. I have used a handful of other wireless mouse's over the last few years and this has been the best one. Great price point and it has the option to connect with a wireless USB, Bluetooth and wired connection.

Solid mouse for the price, I had one previously start double clicking after about a year so expect that to be its life expectancy.

Love this mouse. It's the best mouse I've bought because I can use it for work, and personal by flipping a switch. The battery level indicator is a bit off and programming the light pattern only works when when it's corded.

The mouse itself is not bad. The usb cable is bad. The cable has this extra plastic bulk so plugging into tight spaces is not possible. The reason this is 1 star is ICUE. The software will not update the firmware on the mouse. Every time it was attempted it would fail and cause the mouse to be not detected. No big issue, but then ICUE keeps giving you pop ups about updating. This seems to be a wide spread issue from reading on reddit that Corsair never addressed on the Harpoon mouse. Will be returning. I was able to update the Dark Core with no issue.
