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

I'll be honest, I like the feel, ergonomics, and mouse overall.The part that they screwed up is quality control of the mouse scroll wheel. It will be fine initially but after a little bit of use, the wheel goes loose and you cant get proper scrolls. Sometimes when you're going down, it will go up a couple times then down again, and vice versa when going up.For that, I gave it 2 stars because scrolling is an essential function of a mouse. If the scroll wheel worked or got fixed, I would give it 5 stars.
