Bluetooth Mouses

Hi guys..I'm just inquiring about these 3 Mouses(Mice?):
1. Logitech MX Revolution
2. Logitech VX Revolution
3. Logitech VX Nano

Questions:
1. Are there any differences in battery life? Cause i know that both the MX Rev and the VX Rev are bigger then the VX Nano ( ..duh..). Does the smaller one sucks up less battery? As if you guys might have seen that I've suggested in other related threads that I'm a paranoid about losing power in the middle of a game, but now I'm just getting to a point where I don't want to be tangled up by wires either xD
2. Someone told me something about being able to use a wireless/bluetooth mouse without the adpter that came with the mouse if you have a bluetooth adapter within your comp, is that true?

Thanks for any responses in advance

Edit: I posted here since I'm gonna be using the Mouse for gaming

 

Let me start with number two for a change; Yes. All three mouses you selected aren't bluetooth mouses though, nor real gaming mouses btw.

They all 3 have different batteries. The Nano uses 2 AA batteries, don't know how long it's suppose to last on them. The VX Revolution uses only one AA bat. and lasts between 1 (heavy use) and 6 months (light use). The MX Revolution has a build in rechargeable bat. witch lasts from one day up to two weeks, and it comes with a docking station in witch you can re-charge the bat.

I have the VX Revolution myself, it's a great all-round mouse and it works fine for occasional gaming. I'm still on my first battery, but when it runs out of juice it's easy to swap with a new one in a few seconds.

 

lol thanks for the answer, for me they just seem the be the best choices since they seem to work best for casual use and possible gaming cause they're very similar to my mx218

wait nano uses 2 and the regular only uses 1? do you mean the other way around? and swtiching is not really a good idea during a game..lol i'm looking at the small one and the big one is cause i even thought i'm used to and much rather get the big one but if the smaller one last longer, then i would get the smaller one..thanks again

 

Yes, the Nano - or small one as you call it - needs 2 batteries, the VX Revolution only one. The're both very nice, but i prefer the VX Rev. over the Nano because it's lighter and it has the extra thumb-buttons witch i really use a lot. It also feels better to hold in my hand, and it was cheaper.

But it all depends on your needs and use, you cant go wrong with either of the Revolution series i think.

 

lol wow..i would prefer the larger one too..since i really like the feel of the mx518 i'm just suprised that a smaller one requires more battery :S but what about the difference of the MX rev and the VX rev? other then the price tags..LOL
