Bayliss XL Autovent for greenhouses.,
This review is from: Bayliss XL Auto Vent Opener (Kitchen & Home)
I bought the Bayliss XL Autovent Opener to replace a more expensive unit which failed after a few months. I have had no problem fitting it or with it falling off afterwards. It is useful to put the device in the fridge for a while though to ensure it is in the fully closed position before fitting. Fitting and removal takes less than five minutes using a cross head screwdriver.
This vent opener does exactly what it's supposed to do and keeps the plants in my 6'x 8' greenhouse safe and healthy on hot days.
One thing to note is that it didn't work brilliantly after I left it fitted through last Winter which was particularly cold for long periods. In future I will remove the unit before Winter sets in. I ended up buying a replacement wax cylinder from Bayliss themselves for £14 and they said they would service my old cylinder which I will keep as spare. I couldn't fault their knowledge or service.
Altogether I would say that the Bayliss XL Autovent is a cost effective, high quality, efficient solution and I thoroughly recommend it.
