Pros: Great balance and weight, slides along the desk smooth as an air hockey puck. Gives a just a hint of inertia. Paired quickly and successfully in Win 7; a rarity in my exp. Mouse wheel gives a satisfying click and has a concave tread which is nice.

Cons: The pros mean little if it doesn't work. It doesn't work. It disconnected about 8 times a day. Had to manually re-connect through services. Rubber wore off. Died after 2 years.

Pros: -Bluetooth
-good battery life
-works on all the surfaces i've used it on, its really nic for when im on my surface while in bed
-pretty good shape
-doesn't get dirty easily

Cons: it isn't the prettiest mouse, its all black without any accent colors on it but this isn't really a big issue for me. I kind of wish it was a bit bigger, i have big hands and the curve thing for the thumb is just an inconvenience for me.

Other Thoughts: I kind of wish it also had an adapter so i could use it on my other laptop that doesn't have Bluetooth. It says it gets up to nine months battery life on the batteries but most of the time i use my stylus on my surface instead of this mouse so im not sure what the battery life is for moderate to heavy use.

Pros: -bluetooth
-extremely comfortable
-responsive when working
-great battery life
-have not found a surface it doesn't work on. (used it on glass,black leather, jeans, black painted tables, brushed aluminum laptop finish, polished wood, and more.)

Cons: -takes a moment to wake from sleep
-will randomly stop working and take up to a minute to start working again

Other Thoughts: -seems to cut out between 2-5 times per day
-would not recommend for gaming but if you're ok with waiting 30seconds for it to work every once and awhile its a pretty good mouse all around

Pros: Compact, good aesthetics

Cons: Will not reconnect automatically, need to remove and readd on every reboot.

Pros: Had no trouble at all getting this working and it is very high quality. Got a great deal on it also. I also bought the RF version. They are both similar in format and fit my hand well.

Cons: none

Pros: Seems well built and set up was automatic!

Cons: none.

Pros: None

Cons: Bought 5 of these devices for 2 different offices. 3 of the 5 have failed.

Pros: The simple fact I no longer have a usb port plugged for a mouse is great for me, The battery life is great.

Cons: Doesn't wake me computer from sleep, once and awhile I have to reset the mouses bluetooth connection to get it to work right. But that is maybe once a month so no to bad.

Pros: Bluetooth
Great Power Management
Great laser tracking
Cost effective

Cons: None

Pros: bluetooth
battery life
responsiveness
ease of use
good feel
included Energizer batteries

Cons: lack of back and forward buttons
scroll wheel is a little tight

Other Thoughts: I bought this mouse for my Surface Pro. Since there is only one USB port on the pro it's best to use non-USB devices and this mouse fits the bill perfectly. For the price, this is a great mouse. I didn't expect much other then a bluetooth wireless mouse and I got a bit more. The mouse feels great and the included Energizer batters are a plus. Most battery operated devices do not come with good batteries so that was certainly a plus. The Surface Pro and this mouse connects instantly after boot up. I have purchased a number of bluetooth devices for my Surface such as a headset and it is great not having to plug-in a USB receiver.
