We had fitted origin bifold doors and origin electric blinds. Both are excellent products and have made a great difference to our house. They are well made .stylish and easy to open and close. Friends have commented on the spectacular difference they have made to our house. We fitted the blinds ourselves -that was not a problem-straighforward but were disappointed with the confusing instructions provided on programming the blinds which we have yet to get right. I wish origin would have another look at this. They could do better by simplifying the instructions and by having a you tube video on how to programme the blinds to open and close to set positions. It would cost zilch Brian and Linda Thomas
