Banggood

First of all, about the service. As it was promised, I received the product in two weeks. The product was packed in a sealed package in a box and in a very proper way. About the product. It has a quite compact design. at the moment it arrived, I tested it on a lamp and on a synchronous motor. As well as the brightness for the lamp as the RPM for the motor were adjustable with the regulator. The regulation is quite accurate. For me the product was for sure a big deal for that price!

32 days from CHINA to ROMANIA by EU Priority Line. Package arrived without damage. Tested with 100W incandescent bulb, voltage is adjusted from 0 to 230V, almost linear. Have not tested yet with something more powerful, but I will try next day.

questionable engineering in terms of the input and output panel, the hinge doesn't open all the way where you can't use a screwdriver to attach the wires

Recebido, Bom preço boa qualidade e aparência, mas chegou um pouco amolada devido ao transporte e má embalagem

Přístroj dorazil v pořádku,ale zatím jsem ho neměl čas vyzkoušet.
