Works great with my Surface Pro 3. Folds flat to fit in the pocket in the carry case I bought for my Surface. Very good battery life.

Positive Review

question:
Its a dongle. What do you want? An audiophile grade usb dongle? Hate to break it to you but while a signal is in digital form, there is almost no chance of degradation of signal short of a solar flare or other digital electro magnetic mishap. Just get anything that will give your USB ports space and save yourself 14 bucks by getting a dollar dongle. I'm gonna say dongle again. Dongle.

Negative Review

So nice to be able to take a mouse with me and not worry about the USB receiver. Plus, when I switch computers for work, the USB receiver fits snug inside with the battery. Highly, highly recommended.<br /><br />Outstanding design, worth every penny. Thank you Logitech.
