Very satisfied. Velcro fastening i did not put, does not inspire confidence. Drilled holes for screws on existing cutouts (had to be disassembled and drilled). Did not immediately understand how the paste dispenser works, pressed on the tube and the paste did not climb. Disassembled the dispenser saw that the silicone rubber with the hole merged (tselochka), i twisted it, developed it and everything worked. The lamp sterilizer works (soldering and chip is excellent), the smell of quartz or as someone says ozone is audible. The only negative in this product is the power supply (9 volts 500ma), if it is constantly in the outlet you will have on then it will be constantly warm, that is, for a long time it may not work (let the small but the load on it). The button on the device itself turns on and off the lamp. He took it to ukrmail. Take it, i definitely did not regret it)))
