Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
The scroll part wasn't steady, the primary light doesn't even turn on as you can see. I hope no one else gets the problem. Due to the restrictions I am not able to return it and I can't get a full refund for this item. Wouldn't recommend.
Best mouse I have owned. No more excuses, I have to admit my lack of talent...but this tradesman can no longer blame the tool. For me the weights are a gimmick but I am sure those with the requisite skills would find them useful. Ergonomics are fantastic, it’s smooth and accurate and there is just something about those buttons that wraps up the whole package. Highly recommend
