Wireless Gaming Mice Recommendations

I'm looking for a new gaming mouse by the end of this year. I have the first generation Mamba and I'm fed up with the battery running out and having to use it wired before the end of the day. I know "wireless" and "gaming" really limits my options here, but I can't stand wired mice because of wire drag and I'm not going to carry around a bungee. I'd prefer for it to have a rechargeable battery if possible, but I don't mind getting some rechargeable AA or AAA batteries if the mouse is worth it. So far I've considered these:

Logitech G700 - seems like the reliable choice but looks bland.
Gigabyte Aivia - haven't done any research on this.
R.A.T. 9 - the new colors look pleasing but EXPENSIVE.
Razer Orochi - bit small and uses dry batteries.
Razer Naga Epic/Star Wars - won't use many of the buttons and Star Wars not my thing.
Razer Ouroboros - was going to pre-order this but decided to wait for more reviews.

Does anyone have any experiences or comments with these? Especially in regards to the battery life? I'm also open to suggestions on other mice, or of any upcoming mice that I'm unaware of. Thanks!

 

I have both Mamba 2010 and Ouroboros. Mamba uses a special battery that you can't recharge it without the mouse itself, which is really a turn off point. I think you can get higher mAh battery from eBay. It's non-oem though.

As for the Ouroboros, it's not a perfect fit like the Mamba but it's ergonomics enough. It can lift up to fit your palm pretty well. And the best thing is it uses rechargeable AA battery. So you can buy a bunch of rechargeable AA and just replace it when you run out of battery w/o having to plug the cable in. The battery is not extremely accessible like the RAT 9 but it doesn't take much time to replace.

I don't like the Twin sensor on Ouroboros though. Sometimes it takes quite a bit to calibrate and the mouse is just dragging on the screen. Quite a pain in the ...

 

I didn't know about the battery on eBay. It seems like only a ~10-15% improvement but thanks for letting me know. I can see how the Ouroboros is not as comfortable because they had to make it ambidextrous.. How do the weight of them compare, and how long can it last on a single charge?

 

After 2 years of using the Mamba, I figured out the battery has deteriorated enough for me to get a new one .

The 2700 mAh battery that came with my Ouroboros last around 5-7 hours continuously using it. I never pay attention to that so it's just an approximation. The Ouroboros is a little bit less heavier than the Mamba, not much though.

 

I have the R.A.T. 9. Really good mouse. Expensive, yes. But worth it in customizability. The only drawback is that you'll have the change the battery everyday. It takes about 40 minutes to charge up, but will only last you for 12-14 hours of continuous use. That's alright though as it comes with two batteries & you can always keep one charging while you're using the other.

DPI settings are great (the modes). The precision button works good too. I would recommend getting this one if it falls within your budget.
