Automatic Greenhouse Window Opener Autovent with Opening Force 7KG Opens from 17-25C

Arrived on time and well packaged.This item was bought to go on a new build Outsunny 6 x 8 polycarbonate greenhouse.Easy to install by following the instructions supplied.Fitted very quickly and started working within 30 minutes of installing.This auto opener is very well made and feels quite robust. instructions are easy to follow even if you have never fitted one of these before. We set the arm to the temperatures they suggested in the instructions and it seems to be spot on. As the heat inside the greenhouse increases or decreases the arm slowly opens or closes the window.Fitted easily onto the polycarbonate panels and aluminium frame without any issues.Very clever design that gives peace of mind by automatically opening/closing your greenhouse window.I would highly recommend to anyone with a greenhouse especially as the price is reasonable.Very happy with my item thank you.5*Kind Regards.

Instructions are good but would definitely recommend watching a YouTube on how to install. It made our lives easier as it could have been tricky otherwise. Once fitted product is brilliant and does the job. It's like magic opening and closing on its own

The fittings weren't compatible with my greenhouse, but after some tinkering I managed to fit it. Other than this, assembly was relatively easy. Very sturdy, high quality, performs exactly as it should. Good value for money, very happy with my purchase.

Easy to fit and works as expected

So easy to fit and does the perfect job.

This is a good quality product. It is a bit fiddly to install, but not that bad. It works well. When strong winds are forecast, I will disable it by unscrewing the cylinder, which takes a minute or two. Incidentally, this is the Orbesen Teknik opener, it says so on the cyclinder, but sold under a different brand name.I was worried about rain getting in and causing blight on my tomatoes. However, I have fine netting over the greenhouse which should prevent that. Time will tell.It is fitted on a Halls Popular greenhouse.Delivery is very fast with Royal Mail.

Easy to install and works perfectly, opening the greenhouse window when needed.Has been in place for a fews weeks and is well made, good fit and great value for money

Really easy to fit, without having to drill any holes. Just needed a screwdriver. Worked perfectly on the first warm day after I fitted it. Can be adjusted to open at different temperatures, with a bit of trial and error.
