Bought a twist & go blind for the bathroom window to avoid drilling into tiles. I found it a bit tricky to install, but other half sorted it out and now it's securely in place and doesn't move even when you roll the blind up and down. Knocked off a star as the Blinds 2Go logo on the bottom edge of the blind that is always visible was glued on at a slight angle which annoys me every time I look at it. Otherwise, good product, good prompt service.
