I have bought many blinds from iseek over the years and have never had a bad experience yet. Not being all that good with metric Michael helped me work out exactly the measurements I needed for my old,hard to work out windows. I had previously installed a whole house full of the screen and roller blinds on my own in our holiday house, which I was pretty proud of. They are very easy to install and if you watch the instructional video that Michael has provided online it is very easy. I couldn't speak more highly of the whole experience and have recommended them to many of my friends.
