Remote Control Ultra Quiet Roller Shade Rod Motor Kit CL338H
[CL338H]

I bought both 2 meter roller blinds and 3 meters motorized curtain tracks. I think the curtain tracks is easy to assemble and works straight-forwarded. The motorized roller blinds has self-protection trick for the motor if you do not put the load on. At first I though there must be something wrong with the item. With the good support from the seller, I understand it is just prevent the motor from damaging. I will recommend this products!
