Logitech G602 Wireless Gaming Mouse

This mouse can be used on MOST surfaces, with very few exceptions. First, the surface must be flat. Dips or bumps will affect tracking. Second, it can't be wet. Moisture can affect the sensor.
It has great pickup from the sensor. It can be used on marble and granite surfaces.
The Sensor: Feels accurate and doesn't seem to drop during more meticulous tasks at work. I didn't care enough to do detailed research on what specific sensor is under the hood on this mouse, but it feels accurate enough for my purposes and offers a wide range of DPI settings.
Sensor can be found in many mice so that's not exactly a point to make, but it is great. Batteries last forever in this and I never turn it off and always have it on performance mode. Has not messed up once.
The adjustable DPI buttons are often useful for gaming. As an example, when playing Overwatch I'll set my DPI rather high when using Junkrat but drop it nice and low for Widowmaker.

Logitech G603 Wireless Gaming Mouse with HERO optical sensor

I've always been a fan of Logitech gear and this is back to basics with a nice design/shape for right-handers.
Highly recommended, for high quality budget gaming or general use. Feels like it should be a lot more expensive than it is.
High precision, capable of matching competition-ready wired gaming mice. You can also toggle between high-precision for gaming that requires it, and low-precision.
The mouse itself has a velvety smooth texture to it and feels very comfortable in the hand.

What customers say about "Size & Weight"

Logitech G602 Wireless Gaming Mouse

I bought this for no other reason then the size. I have large hands and most mice are just too small. Even the ones that look or say their bigger just aren't big enough. This one is! It's longer then almost any mouse, has good height/depth, and is fairly wide as well.
For a person with regular sized hands, I definitely recommend this mouse. Logitech has produced another great product in this mouse. But for those with smaller hands, think twice before you buy and do not expect to be fully satisfied if you do.
The size is big. I think it's the biggest mouse I've ever used. But it fits my hand perfectly - my palm rests on top, instead of that awkward spider-like squat my hand performs on medium mouses.
Either the material has changed with use or my hand has adjusted its grip size for the mouse; probably the latter. The only problem is it is difficult to reach all 6 with out contorting your grip. There is also a hard/sharp plastic feel to them.
The biggest drawback for me was the size and shape. I wear size medium gloves pretty much in all types of gloves (winter, snowboard, latex, etc.) and with my palm at the base, my fingers only reach 3/4 of the way to the front.
I am warming up to this mouse now after having it for a few months. I came from a MX master and had a tough time getting used to the smaller size.

Logitech G603 Wireless Gaming Mouse with HERO optical sensor

The best feature is adjustable weight by either using a single or two AA battery.
The ergonomics is perfect for right-handed people, and the weight is evenly distributed.
It's a very nice shape for my hands being an average fella.
Really good mouse. A good size, similar to my previous. The mouse is heavier than similar wired mice but you can run it with one battery if you prefer the lower weight.
It feels cheap, too light and too high, it should be a bit lower.

What customers say about "Connection"

Logitech G602 Wireless Gaming Mouse

It's much more ergonomic, fits very nice in hand, battery lasts forever, there's 0 lag or connection pause even when coming form sleep mode.
The mouse is plug and play in that as soon as you connect the USB receiver, it allows you to use the mouse to at least download the software for more customization, unlike other mice where you cannot use the mouse until you install the software.
side from that there seems to be some wireless connection inconsistency. Some times the mouse feels laggy, maybe its due to my internet router sits right in front of it...
I have had no problems with connections dropping either. I think I would give this 4 or even 5 stars if it fit me, but it just does not.
That's how long I've owned this mouse. Now, all of a sudden, it has trouble maintaining a connection with the receiver at the back of my computer. Worked perfectly fine up until this point.
The receiver for this device is another story, unfortunately. Mine broke after 4 months of use. It's connection became spotty and eventually just stopped working outright. This was a bummer, as I really enjoyed using the mouse.

Logitech G603 Wireless Gaming Mouse with HERO optical sensor

Whilst it does have a bluetooth connection option the usb dongle with its advertised 'Lightspeed Wireless' technology, it feels just like using a wired mouse at any reasonable distance, with no detectable lag.
The wireless range quite impressive - allowing me to operate my computer from the ground-floor living room.
It's portable, with Bluetooth and wireless mode that you can toggle with a button on the bottom of the mouse.
The wireless connection is far superior to my old G700s and feels as though you're using a wired mouse, no skipping or stuttering at all, as smooth as butter.
Excellent build quality and the connection is very stable switching between PC and Mac are seamless.

What customers say about "Features"

Logitech G602 Wireless Gaming Mouse

I love that I can program buttons to many applications or games, super handy. Also, very happy it doesn't look like something from an alien movie. This design is much better than other gaming monsters I've seen.
The software is good, and one of the main things that sets these apart is that the actual programming of the buttons can be stored on the mouse, so you don't need the software installed on the computer you're using once you program the buttons.
The added buttons are easy to program. I have mine set for previous and next tab.
The software is okay (UI is awkward and not clearly labeled for each button), I am a programmer so I can assign mouse buttons to copy, paste, page up, page down and the shortcuts for "go-to line" in my programming environment.
The optional button customization program is another bloatware FAIL from Logitech. As usual, it is a very large download, and PC resource-demanding for something that should be so light and dead-simple. It seems to be causing conflicts while left running.

Logitech G603 Wireless Gaming Mouse with HERO optical sensor

It also works like a dream on most surfaces (even sofas) for couch use in front of a tv/pc set up, due to the advertised 'Hero' optical sensor which is extremely efficient in power and sensitivity.
The battery life is also known to be extremely good as it runs on double A's which can just be replaced, with estimated 500 hours or much longer if the power saving mode is used.
All the buttons on the mouse feel great and the buttons on the side and really well placed and are easy to access.
Terrific battery life - you won't be troubled to recharge for many, many months (apparently up to 18 months) - and no need for special charging mats or cables.
The Logitech software allows all kinds of customisations, from DPI to button configuration and profile management for this mouse. Perfect
My main problem is that the mouse wheel does not have a left and right movement on it. Pretty much a must when gaming.
