This product works if the screw can fit into the mounting brackets. I had to return the first order because it didn't have the screws or mounting brackets. This order has them but one brackets fits correctly with the screws but the second bracket doesn't allow any of the screws to connect. What type of product doesn't make sure brackets and screws match up. Looks like I'm returning it AGAIN

It worked well for my cold-frame for a couple years, before it broke. The metal used is some pretty low grade pot metal for the connection that broke. I'll probably fabricate something stronger and see if it will last a bit longer. I did order a new one in the meantime (I'll update this if it it comes with a better part).

Better quality and stronger parts than the one supplied on the Costco greenhouse, little bit on the costly side, but check around these things are not that cheap.Works perfectly.Easy to fit, easier than the Costco one, hah., and yes does fit wood too, has fittings to work with metal or wood (at a minimum).Looks fine.

Super sturdy, much easier to assemble than the one that came with my greenhouse kit. I replaced my previous opener because it snapped in the wind. The Anleolife is built from much thicker metal and opens wider than mine did. Ordered a second to replace my other old one.

ok, so this is going on a palram mythos greenhouse, which the box says it will fit. Well, sort of. the bottom bracket has a variety of hole sizes, so yes that fit the existing bolts fine. The upper bracket--not so much. I had to file those larger to use the bolts that fit the greenhouse frame. The instructions are a bit vague. It says if your vent opens more than a certain amount to use the upper hole. Well, a mythos vent will open more than 90 degrees, but apparently the company meant for you to check how far it will open AFTER you install the bracket but before attaching the opener bit. I found it impossible to screw the piston into place until I moved the setting to the 2nd hole. It is opening and closing fine, although I wish it would open the vent wider. it is 84 degrees today and the vent is open 9.5".

If you are getting this to replace one that is broken before you take the old one off pay close attention to how it's installed it's not the easiest task to install unless you play close attention to the assembly of the old one!After multiple attempts to install I finally got it and it works as advertised!

We installed 5 of these on the lift-up (2) and lift out (3) windows of our shed-attached, lean-to greenhouse. We’ve had them about a month now and they are working great! They automatically open the flap windows wider and wider as the temps in the greenhouse rise during the day. And close them as temps drop in the evening. We installed the heavier duty (for 30 lbs and under)—which installed fairly easily although the instructions were a bit vague—and have had no issues at all. We are very happy with this purchase.

I bought 4 of these, 2 for the upper wall vents and 2 for two of the five side windows. The only hard part of the install was getting the little hair pin to go through the hole in the piston.My upper vents open out at the top so gravity is working to open them not close them and the springs were not strong enough to pull them closed so I had to devise a system of counter weights. Trial and error, it looks like a weight of 7 pounds on a cord through a pulley pulling each vent closed is working but I will let it run for a couple more days in case I need to go up to 10 pounds.I will buy 3 more for the other side windows after the holiday before the weather gets warmer, and I’ll be adding shade cloth over the roof before summer, but it seems to be working well for now and keeping the greenhouse in the 70s on sunny 60 - 70 degree days. And, despite another commenter, no problem with wind. We had 40 mph gusts today (which is not that high for our part of Texas) and absolutely no concerns.
