I have been using this mouse for about 8 months now.
If price is not a concern, this is definitely one of the best wireless mice you can purchase.
> Excellent shape and grip, especially if you like a large mouse.
> Once you have tried the smooth scroll wheel, you cannot go back to anything else.
> Lots of configurable buttons
> Battery lasts 1-2 weeks on a single charge.
> You can also use the mouse while charging.
> You can charge the mouse using a standard micro usb wire
> Works on glass
> Expensive (but all Logitech darkfield mice are expensive)
> Stutters very badly on some types of surfaces. I have heard that this issue goes away if you discharge the static electricity in the mouse by removing the battery and clicking all buttons for ~30 seconds, but some types of surfaces are just bad for this mouse.
If you want a mouse that works really well on any surface, try a Microsoft Bluetrack mouse. While they are not as feature filled or ergonomic, they work on all surfaces (except glass) and last for several months on 2 AA cells.
Very good mouse

I got this mouse for ergonomic design. It has done a very good job to reduce the pain in my hands a lot. The hyper scrolling functionality is also good. I was able to use the mouse for around 2 weeks before recharging in again.
Infibeam's delivery was really good. The product was packaged nicely with lot of cushion material and was delivered quickly. I ordered on Friday night and got it delivered on Monday afternoon.
