One of the best investments I ever made. No issues, great functions and features. Easy to modify the sensitivity and set multiple pre-set sensitivity levels. Can also make the mouse lighter by removing the weights too. Never had any issues with the 'phantom clicks' or mis-clicking. the reviews here are the first time I've ever heard of the issue. Personally, I've had 3 of these mouses over the years and never had an issue (except when I've been rough with them during travel, hence the three mouses but that's my fault, not the product's).
