Packaging and equipment

Supplied in a white box in the manner of a Xiaomi product. The product itself is drawn on the front side, and the dispenser parameters and assembly data on the back. Includes plastic wall mount. It has tape for easy installation, which I did right away. Tore off the barely old mount from the dispenser, which had not lived for a long time, by the way, here is a review on it

The dispenser is made and attracted attention with just this round body made of white plastic. Front round black display and nothing else

In general, this gold strip serves not only for decoration – it is also a button for turning on / off and viewing data on the display. The strip has a motion sensor and a rubber foam nozzle.

On the side is an uncovered TypeC connector for charging the battery, I could not check the capacity, by the way. And on top of the filler neck for soap. It is covered with a silicone stopper, with a silicone handle. There are no complaints about the assembly. At first glance, everything is sound and strong.

On the back of the dispenser there is a sticker about the model and 3 tabs for installation on a wall mount. Assembly screws are visible.

At first I liked the dispenser very much, it gives a strong stream of thick foam, shoots it straight. The foam is also excellent in detergent properties. I dilute the soap with water in a 1: 8 ratio and it works great. But I use thick soap.

And I was about to rejoice at the purchase when the dispenser stopped responding to my hand. He began to work only on white objects. I thought it was okay, you can get used to acting anyway, but, unfortunately, after another week, he completely stopped reacting to objects.

Then the thought came to disassemble it and look what was inside.

A good idea to assess the possibilities for renovation. I decided to share with you. It is easy to understand, 4 screws, and then everything is on scotch tape. Screw-on boards
