Sven RX-590 SW wireless mouse. Compelled anti-review with disassembly

I decided to share my impressions of my purchase of the two-mode computer mouse from the famous manufacturer Sven. I was and am sympathetic to this brand. I like their acoustics to this day. The mouse was supposed to be a success. It can work via Bluetooth and 2.4 GHz. At first I liked it. But the joy lasted about a month.

The mouse comes in a transparent plastic blister. It comes with a manual, a typeC cable for charging and a 2.4Ghz adapter.

The mouse is made of nice plastic, lightweight and well shaped. On top there is a company logo and a picture of Bluetooth.

On the front is a slanted trigger on the main buttons.

On the side of the two buttons forward and backward

On top of the scroll wheel, covered with rubber and change buttons DPI

From the front end of the connector TypeC to charge the battery

On the bottom model information, eyelet sensor, compartment for USB transmitter and connection mode switch

The mouse can be either in radio transmission mode, or off, or in Bluetooth mode.

I liked the mouse, it is comfortable to use, connected in parallel to the PC via USB and to the TV set via Bluetooth. It seemed to be fine, except that the DPI value is small, but in general it was not a problem. But after a month, the scroll wheel suddenly stopped working. The mouse, as far as I know, was not dropped, not bumped.

I decided to see what the problem was. Tear off the stickers on the base, there are 2 screws.

Then take it apart into two halves, there is a plastic case with button supports inside

I decided to take a closer look and see why the wheel doesn’t work. It turns out that the scroll wheel is attached to the encoder by a thin plastic rod, about 2mm

It burst from seemingly normal load.

Anyway. I had to fix it with a metal clip fused to the plastic. and it worked, but again not for long. For about two weeks. Then the sensor just stopped glowing. In any mode. I couldn’t look it through and the mouse was buried.
Even renowned manufacturers are starting to save a lot of money on materials. It’s even possible to get on a defect or sub-quality materials assembly even of eminent manufacturers.
Specifically, this model seemed good, but with it I was waiting for disappointment. I do not recommend to buy.
