First the negatives: I don't recommend anybody buy the corded option. I bought 2 of these double cellular blinds with corded option and tension controller with an outside mount. The problem is, the cords come out of the front of the top of the headrail instead of out the bottom. I assume blindster did that to keep the blind size basically the same as the headrail length. But now if you mount the tension controller on the wall, it actually sits a few inches BEHIND (from a depth perspective) where the cords comes out of the headrail, and so the cords will rub against the headrail and the blind. It took me awhile to get hold of blindster support, but finally got somebody on the phone who put me on hold, discussed the matter with the product team, then came back and suggested I put shims or spacers or something to get that tension controller out away from the wall. I've attached a photo of what I built myself and what the cords look coming out of the headrail now that I've fixed this, mounting the UTC 6 inches from the wall. But it was all a bit of a pain. Bizzare - as if they just came out with this corded option recently and had not thought this through? Was also quite dissappointed in how it took 2 emails and 3 days to get ANY email response, and then that inital email response was quite off track from my question. Finally had to call 4 days after my initial email.
But on the positive side, now that I'm done with that mess, the blinds themselves are actually quite good. I needed really good blackout for south facing windows to keep the room cooler and they seem to do an EXCELLENT job of that. So I would think if anybody skips the corded option and just orders the standard non-corded, will probably be quite happy the blind, which I am. Hardware and mounting is decent too.
