Unlike on all the seller pictures in reality the light is tiny (check actual dimensions in cmin). When the delivery arrived I thought it was an A3 letter. Assembly is quite straightforward if you have an engineering degree and can translate from Chinese. It literally says “connect 1 and 2, fix it to the ceiling, connect and done”. If by some miracle you manage to get it done the light itself is quite bright and it can be controlled with the attached remote.
