I order the second time, the first mouse worked for a year and a half in the office, with daily use of 8-10 hours. Batteries last for a week. Delivery to Belarus is fast, for 3 weeks. The goods are completely satisfied.
The mouse came quickly and connected immediately. But already getting out of the box was noticeable factory marriage of painting + power cable is also defective (it is impossible to insert into the mouse connector for charging). In addition, there was a feeling that the goods bu, because. On the legs of the mouse are visible scratches. LKM and PKM are really almost silent, but all other keys put straight noisy. The main minus, in my opinion, is that the mouse takes the movement even at a height of 5 + centimeters from the table. That is, when you raise the mouse to transfer to a friend part of the surface-it takes it as if you are leading it on the surface. Summing up, I can say that in this device only two pluses. Battery and silent LKM \ PKM. Everything else is minuses. I advise you to find another option for purchase.
Brought as quickly as possible. In Nizhny Novgorod there was a parcel in a week. At the store at the cash desk. Quality is super! Definitely recommend. One has such already use 3 years, took another one
