Does what it is supposed to do. Little fiddly to assembly the pin which hold the ps=ush cylinder to the push rod. Works Ok, and adjustment is easy for window opening range.

There is nothing wrong with this product, except that the fixings are for wooden greenhouses and if bought for aluminium greenhouses you will have to make your own brackets or other fixings. It took me about 6 hours of solid work to fit 4 of them. this included removing glass and frames to drill the aluminium and lots of fiddly work trying to fit bolts that would secure the openers in a way that would not keep damage the glass as they open and close. Now installed they work really well - effectively opening to a wide aperture each day and saving my plants from being burnt to a crisp. If you enjoy trying to find ways to fit them, fine, but otherwise worth paying extra to get some with clamps designed to fit aluminium frames.
