Review: Easy to fit, works well - As the title. Well built, simpler to fit than I expected and works well. Only thing I changed was the plastic 'pin' which connects the vent arm to the push rod - I was finding when it was 25 degrees + the plastic pin was bending and the securing cap came off which the stopped the louvres closing. Replacing the pin with a thin bolt and nut kept operation the same and overcame this problem
Review: Reliable greenhouse louvre opener... - Purchased 2 openers...very pleased with 1st opener, had to drill out 2 rivets from existing handle, & drill a couple of small holes for new opener. Working perfectly! Couldn't fit 2nd opener as tomatoes were in the way...have to wait till autumn...lack of planning!

### ⭐⭐⭐⭐ almost perfect
*by M***N on 9 June 2018*

Have fitted two to a Vitavia Phoenix greenhouse - easy to fit - working very well. Only issue is that the lever falls off the pin occasionally, possibly because of some alignment issue. However, this is easy to fix with a small bolt or split pin. update Easter 2020 - still working perfectly
