On balance, I'm very happy with my Magic Windows. I'd always wanted to install them to lead on to the deck. Nothing beats being able to push them all the way to the side to open up the whole wall to the outside.
However, I'd have to note that after my order was placed, if I had a question or concern, receiving a response from my sales representative was scattered and unpredictable. It seemed to be a case of "we've got your order so we're not as motivated to respond to you". That may be overly harsh but that is how I felt.
The windows were installed quickly one afternoon by workmen who had obviously done this many times. They took the time to explain to me how to use them and what to watch for re: maintenance. I asked them if they clean the windows and they said "no" but I guess I can't blame them. LOL
To be clear, I haven't used the windows yet at all since it's wintertime and the deck has not been built yet but come this spring I'm expecting them to get a lot of use. I hope that they last me for many years of happy and easy use. A. Spalvins - Toronto, Ontario.
