I do not advise buying this mouse. This mouse cost 6900 The service center sent me a refusal to refund or warranty repairs, although this mouse has a 1-year warranty. They said that they did not find a marriage.

Good sensor Cons: The rubber bands peel off. The glue that is under the rubber bands when moving and pressing on the mouse comes out and everything is in this glue. The main drawback is that something happened to my mouse after 6 months of use. The left button clamp worked every other time and looked like the computer was lagging. And for two months I thought that something was wrong with my computer. Until I changed the mouse .
