Comfortable in hand
Reviewed in the United States on June 10, 2021
This review is for the 'Classic Grey' LeadsaiL LX-002 model:
At 4.1" inches in length, this mouse feels pretty comfortable in my normal size man hand, although I do wish it was slightly longer (I've found 4.5 to 4.9" to be the most comfortable length for my hands). The left and right click buttons are quiet as advertised, but the two side buttons are a bit louder than the 8 other mouses I've used so far. The scroll wheel is sturdy, it has teeth to it, and it's easy to click on without accidentally clicking one of the top buttons too. The smooth gloss top finish also makes it easier to clean compared to the soft touch matte finishes prevalent on other mouses.
Unfortunately, the unit I received has what I am assuming is an annoying defect that I have not experienced in any other mouse. That is, when the battery is low, the cursor will start moving/jittering by itself uncontrollably which is very frustrating because it's basically completely unusuable in that state and happens suddenly. Other mouses I've used will simply have an LED that starts flashing as an indicator that you'll need to recharge it once you're done for the day.
If you're lucky enough to get one of these without any issues then there's a good chance you'll be satisfied with it.
