Feedback-wise all very good. No complaints at all. Not only would recommend but plan to buy another one in a year or two! Happy for you to put me down as a demo person and when the house(s) is finished you’d be welcome to have a video of the doors opening / closing as you have on your website as the views will be amazing.
