Pros: Great mouse. LOVE being able to connect 2 devices. Touch gestures work great. Charges fast and a minute of charge when it is dead gives you at least a couple of use.

Cons: Takes about 2-5 seconds for devices to recognize it when you flip the switch, but that is the nature of Bluetooth, so didn't knock an egg.

Pros: Nice solid little mouse. Looks slick!

Cons: PLEASE NOTE: This does NOT come with a bluetooth adapter.

Other Thoughts: Really surprised a $70 mouse does not come with the adapter needed to use it. I realize many laptops have bluetooth already, but I think an adapter could have been included to make this a 5 star product.

Pros: Small, solid, good battery life, useful gestures

Cons: Single top button, no tap-to-click.

Other Thoughts: Picked this up at the local Blue and Yellow retailer as it was on sale for $20 less than Newegg. The added gestures are a welcome addition to Win 8, though you lose touch-to-click in the transition. The body of the mouse is made of aluminum, so while it doesn't feel HEAVY, it still feels really solid in your hand. It's also TINY! On one side, it's a portable mouse, so that's a positive. On the other. . . . I may wish it were either 3/4" longer and MAYBE 1/4" thicker. . . or both. I use the thing with 3 fingers, which means I have to take my hand off the mouse more often than not to use some of the built in gestures. There are some that complain about losing connection intermittently with this mouse. For those experiencing this issue try turning off selective suspend on the bluetooth device in windows device manager. This SHOULD alleviate most if not all of those problems.

Pros: Small (also a con), thin, bluetooth, dual pairing, works with Mac (you don't have to buy the Mac version if you don't like white).

Cons: Small size (can be too small for normal to large hands), small surface area hard to use gestures on, and it has a NOISY CLICK! Right/left/middle clicks are very loud. They could use to redesign the clicker to be more silent.

Other Thoughts: Overall, for a bluetooth mouse, if you're primary need is small and thin (and for it to work with 2 devices) then this is a great mouse. No problems with that. Clicking is noisy. No getting around it. I find it hard to use gestures on the mouse because it is so small and it also tends to move around when using gestures.

Pros: Super thin.
very well built.
Great touch response.
I really like the ability to set up two separate Bluetooth connections.
really good battery life.

Cons: none

Other Thoughts: I got this to use with my MS Surface Pro. I wanted a small portable mouse that did not have to use a USB dongle. I found this when I was at Best Buy using one of my Christmas gift cards.
This mouse is the best portable mouse you can buy in my own opinion at this moment.
Good job on this one Logitech!
