Ergonomic Wireless Vertical Mouse Left Handed

Super fast delivery, good quality and d good price. Works well as expected. Very happy with the product.

comfortable to hold and use.
just as advertised

The box was a bit wrinkled on delivery, but the mouse didn't seem to be damaged.
Despite the large appearance, it was very light.
But, a little unstable, a little wobble on the right front corner.
The forward-back buttons work without drivers.
The toggle/change button is on top. But there is no indication what DPI is set now. You have to count the clicks.
The light line is constantly on and changes its color (I couldn't take a picture of the color). There seems to be no way to turn it off.
On the highest mode the cursor runs very fast. I have to reduce the sensitivity in Windows.
The buttons are a little high. When my hand is relaxed, my index finger falls on the middle key, not on the top one, as I would like (see the photo). And the mouse itself is a bit wide.
If anyone is interested, in standby mode we consume 0.025W, and in movement and scrolling - 0.1W.
In general, it's a good item for this money.
