The product is mediocre, despite being my first ergonomic mouse. It takes a while to connect via wireless pen, it is not instantly responsive, and it's a bit awkward to move around. Delivery was within the expected time.
Arrived quickly! Very convenient, for about 14 Euros it's a great item! Charged in a few hours, has been working for about 10 days now. It turns itself off and on with a press. My hand no longer hurts like it did with a regular mouse!!! BUT there is a small defect, the front right bottom point was slightly higher than the other points, I glued it with tape (red in the photo) and everything became even. The speed of operation is normal, but you need to get used to it!
The package arrived a little crushed, but the mouse itself arrived intact. It is made of good material, is lightweight and very comfortable.

I've only been using it for three days, but it seems very good so far; the only thing I regret is not having ordered the wireless version.
