Pros:
It's really small and It is version 2.0, aparently It is a con, but It you think about, the most bluetooth devices (mouses, keyboards,...) don't need a hudge amount of data and speed, for these devices, 2.0 is enought and prefered to 3.0
Cons:
I can't think about anything against
Bottomline:
If you need a bluetooth (you don't have one in your pc), this or the round one is the best option, I am using for the mouse in a pc connected to the tv and without cables the thing is totally different and better (Posted on 1/25/12)

Pros:Inexpensive, convenient, easy to use.

Cons:
no
Bottomline: You can connect the netbook and not by accident that volnovatsya slomaesh. He hardly stands for the face. (Posted on 11/27/11)

i was a little uneasy at first, but at the end of the day these things work great. I am able to transfer all my files from my phone to my new laptop i just bought. This is a great item for a great price. I recommend that you buy this item. It is small to so that also is a key factor. (Posted on 9/4/10)
