Wireless mouse for a laptop

I'm looking for one.

Criteria:

Ergonomic shape and size. Preferably something like intellimouse, but everything that is not tiny is ok. 

Sensor should be good enough for gaming. I don't need super precision, just something that does not make you want to throw it at the wall. DPI is irrelevant.

Good quality feet. Generally anything that slides, as in, no plasic feet that you can see in cheap mice.

At least two months of battery life with batteries or a week with built-in accumulator.

G602 and G700s would probably be good at all of that, but they cost over 70 euros which is twice what I paid for G400 that I use on my desktop.

So, my question is, is there anything good under 40 euros? I was looking at things like Logitech M525 and other M5** and M3** series mice. Is there anyone who used them? I'd like some feedback.

I just bought a Logitech Marathon Mouse M705 to keep on my night stand.

Good build quality, nice shape, not too small but slightly smaller than my Mionix Naos 3200, claims 3 years of use on 2 aa batteries so it should at least last a couple months, slides well but not as well as my mionix.

Downside? the sensor is way off centre so it feels very strange to me. You may get used to it though.

Mionix Naos 3200 feels great but is corded and requires drivers for some features. I don't think they're too expensive though.

I already have a decent wired mouse. It's inconvenient to connect it every time.

I never used a mouse with this sensor placement, so I'm not sure. What about precision and latency in games? Can you play an FPS with it?

I'm not sure how it would go in an FPS because I really use it as a secondary to control stuff from bed. I'll fire up CS:GO and play a few arms race matches with it. I'll get back to you in 20 minutes.

Precision felt good. It does feel like it has way to much latency. I don't know whether it's the off centre sensor or what but it just doesn't feel right for CS:GO. I did get plenty of kills with it though so it works in that sense. I'd look for something similar but with a centred sensor.

Okay, thanks for your time.
