Rollerhouse Roller Shade Motor Motorized Systems for Interior Shades Motors Radio, Wireless, Quiet, Compatible with 1 inch Shade Tube

These are very sturdy, clearly well-made pieces of kit. I swapped out the piece that slides into the blind to match the size of my blinds (a simple process using supplied parts), charged them up, slid them in, and then set up the remote and they worked perfectly first time. Great product, would buy again.Customer support are also helpful if you do have any problems. I bought two motors and one of them turned out to have a dud battery, so the seller sent out a replacement for me, no quibbles, no probem.
