"World's worst mouse"1.0 starson by Big_nerd
Pros: A slim design And thats the only pro
Cons: big dongle (easy to break)
Dongle screws up after 1 day to 3 months if your lucky.
optical light in mouse breaks if your not careful putting the battery in.
Summary: If you buy this you're the dumbest person ever. I've honestly gone through 7 of these but the store i bought it from wont even give me a $35 gift card. I'm just going to buy a Logitech Mx 1100 as they are supposed to be great.
The bottom line i would have to say is DO NOT BUY MICROSOFT WIRELESS MICE OR KEYBOARDS, they suck. Logitech is the way of the future.
Thank-you and hope this helps you alot in the decision that you make when buying a wireless mouse.
