The blinds are great, the price was good and your customer service after I realized I measured wrong was top notch. My issue is with the brackets that come with the blinds. Yes, the left bracket can be mounted easily before the blind end is inserted into it. The right bracket needs to be attached to the blind, swung up, the blind needs to be leveled and then the bracket needs to be screwed on the wall. Only problem there, the blind roll does not give you room to drive the screws in. If your installing a 3' blind you may be able to mount and level the brackets but when your talking 139" like I ordered, it's not going to work. I welded a 4.5" piece of metal to all the brackets, drilled holes and that worked for me. I was able to get the blinds up, leveled and screwed into the wall with ease that way. Something to think about, extending the bracket attachment points.
Response from Blindster
I'm sorry you had problems with your installation. It is sometimes difficult to level a roller shade that is 139" wide. We usually recommend that you mark the place where the screws are placed into the bracket with a pencil (while you are leveling the shade. Then you can remove the shade from the bracket, install the bracket and then mount the shade. Thank you for presenting an alternative solution.
