This is Logitech's only other Bluetooth mouse (V470 was the older one) and it definitely has its upsides. It's priced the same as the V470 (at least from the store i got it from) and there are some improvements over the older Bluetooth V470, but there are some minor issues as well which would hardly bother most people.
Look & Feel
1. It looks sleek with its glossy surface and its overall slim design and not forgetting that shiny silver Logitech logo plate.
2. Due to it's slim form factor, it doesn't exactly have the best ergonomics although the slightly raised back helps keep the rear end steady and this is important because:
3. The 2 AA batteries add a bit of weight to the rear end of the mouse resulting in a slightly uneven force distribution. You will get used to it though, none of these are big issues, just highlighting.
Features & Performance
1. The M555b definitely has more features than the older V470. The M555b comes with Logitech's MicroGear (Hyper Scrolling) technology and an Application Switch button which can be reassigned with the included SetPoint software.
2. The tracking on this mouse is excellent, pin-pointing is no issue and there's practically zero noticeable lag. The mouse fairs excellently on this point.
3. Battery life is nothing to shout about, but it is adequate. (Based on the estimate battery life from SetPoint software).
Conclusion
Need a bluetooth mouse? Get one. It works like a charm and feels surprisingly solid, too for a notebook mouse but maybe it's due to the added battery weight. For the same price as the V470, why not get the newer, feature-packed, better looking one?
