      The vent opener seemed to be working well, but suddenly started leaking and stopped working. Wasted my money on this. I would have expected better quality from a palram product.

      Works perfect to adjust the temp in the greehouse. I don't know what the magic is behind the mechanism, but it was able to help keep the temp stable through the summer

    • great and work well
      Verified Purchase

      Mine didn't really come with anything to speak of making adjustments according to temperature and width of opening, so I just experimented until I got what I wanted. They do work very well to open the windows without being one more thing for me to have to attend to, so well worth the cost. Do be very careful and attentive during installation though, as during assembly, one snapped shut while I was holding it and nearly guillotined my finger tip off, which was quite painful and quite messy and put me out of working on my greenhouse until it healed.

    • Q:

      "Why did you choose this product?"

      • A:

        I've been researching greenhouses and had planned to purchase it from Greenhouse Megastore but decided to check out your site prior to placing the purchase. So glad I did as I was able to purchase the anchor kit, window auto vents, and shelves for only slightly more than the greenhouse itself from the Greenhouse Megastore. Thank you so much.

      • A:

        I've had a greenhouse in another state and had no vent on it, this is needed to let some of the heat out.
