Summary: 1. Razer Advertised the mouse of having a 1mm lift off distance. I can however slip 1 finger under 1 side of the mouse and it will keep tracking. This gotta be a joke, Razer! 2. This mouse uses the Phillip Twin Eye sensor.
Summary: I bought this mouse in September of 2011 - so it is about 6 months old now. I was very excited to get it and was rather pleased with it the first few months. It seems however that Razer product quality has hone downhill over the past couple years.
Summary: Mouse is really fast when it works. After 5 months the wheel scroll stop operating. Then it's been only couple of years the mouse works whenever it felt like. Had to go back to a regular cheap mouse.
Summary: after purchasing my Razer Lachesis from a big name retailer....the cursor started to jump all over the place ..yes i did all the things Razer said to do...the drivers,firmware..cleaning with q-tip...after all this..the retailer would not take it back or give me a refund.
Summary: Not durable at all. Broke down due to clicks after almost a year, which is unacceptable for a gaming mouse. It is not ergonomic for people with short hands either. It should be shorter. I am very happy, that at least i got a replacement from amazon though, thanks to their excellent service.
