I've only had it for a day, but I have to say Logitech did a lot of things right with the G700 mouse. I'm by no means a fanboy, the last Logitech mouse I owned was a very long time ago (the iFeel mouse with Immersion's TouchSense technology, I really loved that feature, it's a shame it never came back).
A lot of the complaints I see online are exaggerated and/or overly critical. Yes, the mouse charging wire could be looser, but it's really not bad. It's actually quite like a lot of wired mice I've had in the past. I think they could maybe improve this in the next generation, but honestly I seriously doubt I'll be using that cable all that much outside of recharging. The battery power issue is to be expected with this powerful of a mouse (1000hz polling rate, 5700 DPI, etc.). One thing you can do to help if you haven't already is create at least two profiles -- one for general use (web browsing, email, etc.) and another for gaming. The profile for general use you should put in "power saver" mode, a polling/report rate of 125 or 200, and a lower DPI setting. That should help with battery power. For gaming you can bump up all of those. I do think they should have tried to squeeze in room for a second battery, but as I understand it the main reason they didn't is because of lack of internal space, so the electronics will have to miniaturize further for that to happen I guess.
SetPoint has a nifty feature enabling you to have it automatically switch profiles based on what program is running, so you really don't even have to bother manually switching profiles (and that also has the benefit of freeing up another button to assign). I also like the lightly textured grip, it's just the right amount to prevent slippage due to sweat. Besides gaming I can see where the power this mouse has will come in very handy for other programs like Photoshop. I also absolutely LOVE the scroll wheel. Please don't ever take away that feature Logitech! Oh, one more thing I just thought of to add. I've seen a lot of complaints about it being too heavy, but it's considerably lighter than my previous Microsoft Laser 8000 Wireless Mouse. In my personal opinion it's just the right weight, I have a hard time imagining it being any lighter.
Overall I'd have to say this is hands down the best mouse I've ever owned. Great job Logitech, keep up the good work!
