I bought six of these for my garage/shop windows. Required more time to move stuff out of the way than it did to install the blinds. They look great, block some of the cold air movement and work just as described. They're great to help conceal the contents of my shop from onlookers when closed, and easily open to allow light in when needed.

Pros: Easy Install, cordless, great value for the price
Cons: Just a bit too long and not adjustable.
