Customer Ratings & Reviews

Works well and no lag. I use it for hours at a time when working from home and have not gotten any cramping on my arm.

I decided to move to a wireless gaming mouse because of my desk orientation and switched from Razer peripherals to Logitech. Very happy with the G603 so far, love the different latencymodes (8 ms vs 1 ms modes for general use vs gaming) and the batteries haven't had to be changed yet months after ownership. Latency hasn't been an issue moving to wireless in games as a heavy PC gamer, and the shape is reminicent of other classic Logitech mice like the G500 or MX518 series mice.

perfect acceleration! long battery life. and bluetooth. good with multi devices

I bought this mouse because I wanted a long lasting, gaming capable BT mouse. Well...I got those, but not in an easy and seamless way I expected. The lag when using BT is enough to make it useless for FPS games and the BT connection itself tends to go to sleep rather quickly, less than a minute or so. This mouse is best used with the included wireless dongle, in which case all these shortcomings are fixed.

I've always trusted Logitech for my PC peripherals. Quality is always good, and this is their best wireless gaming mouse yet with imperceptible lag of 2ms. The batter compartment is creatively under the hood which are magnetically attached to the base. Button functions and with 4 DPI settings, it's configurable more than any gamer would need, absolutely commendable product.

Works smooth with a good size and weight to it. Really impressed with it.

Mouse is the perfect size and perfect weight. Glides smoothly with gaming.

This is a really outstanding design and love it takes 2AA batteries. The cover is very interesting and the software from the site is really good.

Easy to use, no lag, comfortable in hand, easily glides

Only had for a few weeks now but it has so far been great. I have larger hands and this fits perfectly in my hand. Very accurate and I love the feel of the click. So far it has been a great mouse, hoping to get at least a few years of use out of it, if not longer.

I got it for my travel Laptop, really easy to use, great to set up.

I've owned a lot of gaming mouses, most of the razor line ups like the death-adder series, but this one takes the case as my favorite based on it's super low latency, wireless capability and the bluetooth option.

The cost for this is very high. We'll see in six months.

I bought a G603 last year for $40. I like the G603 so much that I thought the "next model up" G703 was going to be even better. However, after owning the G703 for one day, I returned it and bought another G603. I actually paid $56 this time around for another G603 because I like the G603 that much. I was unhappy with the G703 even at $54. Pros for the G603: - Longer lasting design. Mouse doesn't become "unusable" after the non-user replaceable battery degrades. - User Replaceable batteries. I use rechargeable ones. - Feels lighter. You have a choice between using 1 or 2 AA battery. I use only 1.

This mouse is good for gaming and has a great Bluetooth. Once you set it up all you have to do is turn on the mouse and it automatically connects. I love it.

After using the G903 for quite awhile it's nice to have a larger, more ergonomic mouse. The sensor and response is almost as good as wired.

I was looking at wireless gaming mice for a new desk set up where wires were constantly catching because of the layout. Decided to switch from Razer Deathadder to Logitech, whom I haven't used for some time. So far the G603 has been great, with a shape and ergonomics that remind me of the old Logitech MX518 or G5 mice that I used to use. It's still early, so I haven't had a chance to get an idea of battery life but so far so good and I switch it off between uses. Performance is excellent, and I don't notice any difference going from a wired mouse to this one.

The Logitech G603 has awesome battery life, great response via both Bluetooth and USB, and the sensitivity can be set to any level the user desires.

With the adjustable DPI and the two side buttons it’s a really smooth mouse overall, my only issue it fits kind of small in the hands, so if you have big hands I’d recommend the G903.

I like the feel of this mouse in my hand, no lag. Wish it had a few more buttons but that’s just the price point of this logitech.
