Trust Primo Wireless Optical Mouse - 1600 DPI, USB, Black - Ergonomic Computer Mouse with Scroll Wheel for Office, Gaming & Home Use

A nice ergonomic mouse. Comes with batteries & instantly recognised by Windows. There are no navigation buttons, if you're looking for that sort of thing, but for me; that's not a problem, because the issue that I had with my last mouse was due to random navigation, so I'm actually glad that this mouse doesn't have them.Plug-n-play mouse without the tail. Bought as a replacement for my wife. Her previous mouse was also tailess too (confused? I'm referring to a wireless mouse), same brand Trust, but this time a newer model. Good value price, smooth gliding action, and as my young 4 year old granddaughter would say "good job grandad". What better recommendaction than from a 4 year old. Enough said.Hate it. Utterly hate it. The R & L button/pads are loose and have to be pressed through two levels to engage. This is replacing an older mouse but it's going back. Utterly waste of time and money.Mouse would not pair with dongle. Returned.Decently ergonomic, decently priced if it worked properly but at any sort of performance level the response rate drops to less than 50%
