LogitechG602 Lag-Free Wireless Gaming Mouse – 11 Programmable Buttons, Upto 2500 DPI

I bought this mouse about 5 years ago here on Amazon and have used it almost daily for that entire time. It is not unusual for me to use it for several hours at a time. This has got to be the absolute most amazing mouse I have ever purchased. I've been buying them since 1989 and I've never had one nearly as good as this one is, not even close. I even invented one that went to market some years ago, but not one of them could hold a light to this one. I typically sit on my couch and use a circle of plywood for my mousepad. If I told you how many times I've dropped this mouse and watch the battery compartment door come off and the batteries go flying, you really wouldn't believe it. I've dropped it on hardwood, vinyl, carpet, just about every type of floor you can imagine. It's been dropped from as high up as about 4', but more consistently from about 2' high. I'm using it right now with my laptop, and so far I haven't dropped it today, but there's another hour or two of the day left. There's still time.While I don't use all of its capabilities, all of the buttons still work despite a LOT of use. When I use AA Lithium Ion batteries in it, it lasts so long that I can't remember the last time I changed the batteries. The USB broadcaster is still the original. I plug and unplug it every day and it stores in the battery compartment. For that, I'm grateful because I'm sure it would have been lost by now during any one of the times its been dropped. The broadcaster has never failed, and the Bluetooth connectivity is working well. The gliding pads on the bottom are worn, but are extremely resilient. They have many years of service to give. The ribbed, soft rubber wrist pad shows some wear now, but it is still quite comfortable and has a lot of years left to go.Ok, ok, so yes, there is something that is disappointing, but only slightly so. The mouse uses two AA batteries, but due to the way they are positioned, on rare occasion the batteries will drop just a little bit, just enough for the mouse to stop working. However, a quick removal of the battery compartment door, snapping the batteries back in securely, then replacing the battery compartment door, I'm back in business.Would I buy this mouse again? Absolutely. It looks like it is a bit expensive to get hold of one these days, but there's a good reason why. The absolute best, most reliable piece of computer hardware I've ever bought. And I may never have to buy it again. I've never even been tempted to say that about anything computer related before in the last 36 years. That should account for something.

Initial review, same day as I've received it. I'll try to post another review after a couple months of use. NOTE: I've updated some of my thoughts after a couple of weeks of daily use!I'm upgrading from the G400 to after a few years of use because the cable developed a short. I wanted something similar with perhaps a few extra features. The G602 was cheaper than other mice I was looking at and has more buttons, plus it is wireless so I thought I'd give it a go!This mouse weighs a good bit more than the G400 thanks to the AA batteries which power it. You can run it on a single AA battery for reduced lifespan, or run it on a pair of them for more battery life. This will also greatly change the weight of the mouse. I've found I prefer the single battery. The mouse is still rated for something like 110 hours use on a single AA battery. You could get rechargeables and keep one charged ready to go, or just a few alkaline's ready to go in a drawer nearby.Shape is nice for my hand. I tend to use a fingertip grip or a sort of hybrid palm/fingertip. This mouse is almost too big for for the fingertip grip but it has a low enough profile for this to work. Some of the MMO style mice are much too tall for that and seem to be designed mainly for claw grippers. UPDATE: After a couple of weeks this mouse is pretty comfortable! I can easily go with the fingertip grip I'm used to and with a single battery it's not too heavy for that kind of movement (I keep the heel of my palm planted on the mousepad and move just my fingers most of the time).I like the six thumb buttons, they are accessible enough, with the front four being the easiest to get to. I'll need to play around some to see how I like them mapped, but by default the lower two front buttons of this group are the forward/back buttons (G4 and G5 on this mouse) and that seems to be pretty intuitive. I don't use DPI shift but love having those extra two buttons for other stuff. On the G400 they were behind and in front of the scroll wheel and weren't very easy to get to, the new location to the left of the left-click is nice. UPDATE: The buttons definitely work well for me. I still most often use the two that were programmed by default for front/back (G4 and G5) but the others are in good spots too. I heal in my MMO and especially like having my two instant-cast big heal spells mapped to the DPI buttons.The scroll wheel is very nice--one of the best I've used. I don't like my scroll wheels to be very clicky, but also don't want them to be too lose. This one has definite stops as you scroll, but they do not click allowing for very fine control or faster scrolling. There is no free-scrolling option on this mouse like some of Logitech's other offerings.My only complaint about the physical design of the mouse is the thumb rest/thumb buttons. I have large hands and large thumbs and my thumb feels almost wedged between the rest and the bottom of the buttons when I rest it naturally on the mouse. This may be something I get used to with use, we shall see. Other than that this mouse has a very similar profile to the G400. UPDATE: I definitely got used to the thumb rest. It's pretty comfortable. After use, though, I did discover one small point of poor comfort: I hold my mouse sort of skewed to the left. Not sure why. But this makes my pinky rest a little more toward the back of the mouse than is probably normal. Along the sides near the bottom of the mouse in front and back there are some fairly large inward bevels and the one on the right rear side is where my pinky ends up and is slightly uncomfortable. It's no big deal and isn't noticeable most of the time. This probably wouldn't be an issue for most people. That said, I'm not sure why they shaped it that way.Software setup was super easy since I'm moving from one Logitech gaming mouse to another. Plugged in the adapter, let Windows install the driver, and then it was recognized in the Logitech Gaming Software. You have to switch from on-board profiles to automatic game detection on the main screen if you want this functionality (with on-board profiles you get up to 4 profiles that are stored on the mouse and move from computer to computer with you). The games I had set up on my G400 were recognized but since the G602 has very different button layout the mapping was not set up. This only took a couple of minutes to fix. I had to restart the software to make it work in my game, though.Wireless works fine when using the provided extension cord for the USB dongle. It works alright when plugged into the back of my PC, about 5 feet away from the mouse, but does have some slight communication issues at that distance. Sometimes the pointer will jump a bit further than expected.So far here are my pros and cons:Pros:* Mostly comfortable design, similar profile to G400* Nice button layout, definite upgrade from G400* I love that it comes with a USB extension to put the dongle close to the mouse* I also love that it has on-board dongle storage for when you go on the road* On-board profiles for switching between comptuers* Logitech Gaming Software, been using it for a few years now and love it.Cons:* A bit heavy, especially with both batteries* Wireless--hopefully this works out well in my apartment without much interference.Overall this seems like it'll be a good upgrade with a few extra buttons while not going crazy like with the G600.
