Review on Perixx PERIMICE-804 Bluetooth Vertical Mouse - Wireless Connection For Windows & Android, No USB Receiver Needed by Henry Johnston

for this price, its definitely a cheap clone but a good mouse nevertheless. The materials are thinner, and you can feel the difference. The only functional problems are a slightly numb scroll wheel, and the fitment of the usb dongle. While you can plug the dongle into the mouse for transport, it is very loose and protrudes out in a way that guarantees it will be knocked loose when you toss it around in a backpack. But for the price, i'm quite happy.
