LogitechG602 Lag-Free Wireless Gaming Mouse – 11 Programmable Buttons, Upto 2500 DPICarbon Neutral Certified by SCS Global Services

Been using this mouse for awhile now and will compare it to the Logitech MX1100 it replaced...---First, my stats---Primary use: Photoshop, video editing, internet, etc... (not a gamer)Usage: 9 hours a dayHand size: 7-7/8" base of palm to tip of middle finger, 9-1/2" thumb to pinky stretchedHeight: 6'---Comfort---The MX1100 is one of the very first mice I thought Logitech nailed in terms of comfort (larger/taller mouse than most). I've never had any fatigue or issue with the MX and loved how well my hand conformed to the shape of it. Once I received the G602, I knew it wouldn't be as tall, it has a shorter profile so that you lay your hand flatter instead of cupping it like the MX.The G602 is good/great in terms of comfort but not as good as the MX which I would consider fantastic. The wing extending on the left side is a good length and my thumb rests very well on it. The texture of the wing is a textured soft-touch material that has some grit to it, some say it's like a sandpaper or rough surface but I don't find that to be the case at all.Although this mouse is geared towards palm-grippers, I find that claw-gripping it isn't an issue and would be fine for most however I haven't used it in this regard for extended periods of time. I tend to palm-grip my mice but at times will have a hybrid grip between the two and have had no issues or discomfort.---Buttons---The left/right click buttons are very sensitive compared to the MX1100. It barely takes any force to register a click, took me a little bit to get used to at first (maybe 10 minutes), but have always wanted mice to be this sensitive so this is a big plus for me.Button placement for everything is near perfect for my hand size (see stats above). I can reach every button with ease along with being able to distinguish each of the 6 thumb buttons. The thumb buttons are stiffer than the typical forward/back buttons of most mice to ensure you don't accidentally press something.Wish this mouse had the hyper scroll feature at least, but understand why they didn't as it would take sales from their flagship G700s mouse. However, the scroll wheel is fairly decent even though it doesn't have hyper scroll. It will scroll pages based relative to the speed you use, so if you scroll fast it will scroll more of the page but if you go slower it will scroll at a slower rate to give you more finite control. Took a day to get used to compared to using the MX1100, I still find the hyper scroll the superior scroll wheel to use but since this is geared towards gamers, I don't think this is much of an issue.---DPI/Tracking---Tracking has been spot on, haven't had any issues to date. I tend to use the 2500dpi which has been my preference for awhile. If you need more than that you can always increase the setting in your OS to make it more sensitive, I doubt anyone would need to max the dpi and the OS setting and feel they needed more.One of the biggest issues I had with the MX1100 was that the tracking wasn't precise at times. In photoshop, there were numerous times it would skip pixel increments when trying to drag an object or create something to be a certain pixel amount (ie: make a box 250px, but cursor would go to 251px or 249px and never 250px). The G602 does not have this issue.---Construction/Weight---The mouse seems to be very high quality as most of the better Logitech mice are. I can imagine over time the rubber palm/grip area will get gunked up from use and will be more of a pain to clean but time will tell. The materials seem to be a step up from the MX1100, but only slightly as the MX was already nice to begin with.The G602 with both batteries is lighter than the MX1100 and is noticeable. I've always liked heavier mice and even though this is lighter than what I was used to, it still has a nice weight to it. You can always just use one battery to help lighten it if you prefer it to be lighter. Between the two, I prefer the weight of the G602 as it seems perfect.---Modes/Battery life---When doing an A/B comparison between performance and endurance mode, there seemed to be slightly better tracking movement in performance mode, but it was so minor that this was the only way for me to notice a difference between the two. This may be more noticeable in games as I'm sure it reduces the polling rate from 500hz to 125hz, I left it on performance.Battery life is very good and although some people prefer having the ability to connect a usb to charge a mouse so they can continue to use it (like when gaming), I much prefer to swap batteries out (have spare eneloops ready all the time) as it isn't that often you need to.-----------------------Overall I think this is a great mouse compared to the MX1100 for what I use it for and want it to do especially considering I don't use it for gaming. There are some little minor things I wish it had like the hyper scroll wheel and to be slightly taller like the MX, but this is a gaming mouse and understand why they didn't go that route.

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.
