Review on Perixx PERIMICE 520 Programmable Adjustable PM 520 11447 by Scott Rao

Perixx PERIMICE-720 Ergonomic wireless trackball mouse with adjustable angle: one because I liked the purple trackball and two because of the tilt function. The mouse is great because you can connect via USB or Bluetooth. However, it became very sensitive and started having serious connectivity or connectivity issues. The sensor never seemed to read my movements at random times. I was disappointed and stopped using it after just a week. Didn't last two weeks. I was hoping the quality would be good. The packaging was pretty and "German" is probably a marketing gimmick as the packaging had Chinese on the front. I kept the extra purple tracking ball that I bought separately in hopes of potentially being able to use it with the new mouse I had to replace this with, Logitech.
