I have been using it for more than a year, during this time 2 such mice have been replaced under warranty. And now with 3 problems. The quality is complete, in the first there was a marriage of side buttons that began to cling to each other after a month, in the second double click on the left button and the hold on the right button did not work, now the third and again the problem with double click and now with the battery, practically does not hold. Money down the drain, mice for half a year, I will not take more products from this manufacturer.
