Initially ordered two for my 10' x 8' Greenhouse. They work a treat so I ordered a third - leaving one window to be manually operated. The third one came without the fixing screws and pins. Fortunately the initial order had extras. Recommend these for sure.
Very good easy to fit work great
Will do the job. Fitment instructions were marginal.
Bought 2 to see how well they worked. Have now ordered another 2 as they work well. Again the instructions were not easy to follow. The screws supplied were too small for the holes left by the rivets from the manual openers.
Very fiddley to fit but worth having
Does the job nicely. I wouldn't recommend drilling out the holes of the existing rivets on the standard opener though. Just place the opener next to it.
Amazing product, such a clever device
Nicely finished compact product that is performing very well and looks very tidy.
The opener works well, is easy to install, and operated as described.
