Order arrived promptly and all the needed parts were in the bag and look to be good quality. The directions for installation were fairly good. The major problem I had was in syncing the door opener. The instructions did not help and it took a lot of experimentation to get it correctly synced.
I would recommend this company to anyone who wants quality parts at a reasonable price, quickly and a fair shipping fee.
The order processing and the shipping was speedy. Very Commendable!!The rollers appear to be high quality products. Will be mindful of the performance and service that they provide.
