My greenhouse needs the vents open when the temp gets high, and this usually is when no one is home, so we purchased this product to open our vent. And this works like a charm. Would purchase again

the product was defective in that it was drilled on the wrong end. Fortunately I have a neighbor who is a mechanic and handyman and he was able to rebore the correct end so we could put it into service, winter lasting as long as it is. We had a whole greenhouse on hold while we waited for sufficient daytime temps to start our flats. Returning your product was not an option because of time constraints. I think you probably do not want me writing a review that will be published. Now that its fixed its working properly but its a flimsy piece of hardware. I don't expect it to last long.
