This is the first time I ordered blinds from the internet. All other blinds I've always had professionally measured and installed. I measured 5 of them for my first order. I received them right on time. I installed them and they all fit absolutely perfect. I did the same on the second order of 6. One was motorized and even that one I installed and it fit perfectly. Needless to say I'm very happy with their service and the blinds themselves. Even though I'm now retired and over 71 years old.
