I bought the $20 one from Harbor Freight, but it didn't appear to ever work, so I returned it. Decided to pay up for this one. So far, it works perfectly and reliably for about a week now. Installation was easy. I made an adjustment this morning so the closure is now flush. I love having a greenhouse that doesn't need constant monitoring. It's a bit expensive, but all the good ones are. So, until Wal-Mart starts selling these, I will have to live with the price. But, it was worth it to me, to have automatic ventilation. I also like that the hardware never extends more than an inch or two into the greenhouse, which will allow me to build a screen frame that will keep rodents out. Review: works great so far - Most of the openers that I saw on desertcart had the opening cylinder protruding from the back of the opener, which I felt might get in the way. This opener cost twice what others cost, but the cylinder did not protrude from the end. I live in a fairly mild climate which usually drops to the 30's or 40's at night, and rises to the 50's or 60's during the day in winter. Under these conditions, the opener opens during sunny days, and closes at night which is what I wanted it to do. I cant rate its durability yet, since I have had it for about one month. ## Features - Designed to fit most metal and wooden greenhouses - Electricity free using solar power to automatically open and close your greenhouse windows - Built from durable and corrosion resistant materials, annodised aluminium and recycled plastic bracketary - Hand built here in the UK using quality components and guaranteed for 2 years - Lifting force of over 6kg and has maximum opening range of 30cm - Please Note that certain greenhouses may require additional fittings when installing your autovent, Halls and Robinsons Greenhouses fittings are available from the Bayliss Website, along with our other autovent products! ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Bayliss Autovents | | Color | Silver | | Cover Material | Plastic | | Door Style | Sliding Door | | Frame Material | Aluminum | | Indoor Outdoor Usage | Outdoor | | Nominal Wall Thickness | 3 millimeters | | Number Of Vents | 1 | | Number of Doors | 1 | | Size | 1 Count (Pack of 1) | ## Product Details - **Brand:** Bayliss Autovents - **Color:** Silver - **Cover Material:** Plastic - **Frame Material:** Aluminum - **Nominal Wall Thickness:** 3 millimeters ## Images ![Bayliss XL Autovent - Automatic Greenhouse Window Opener - Temperature Sensitive Solar Vent Opener - Image 1](https://m.media-amazon.com/images/I/51pls-bXFnL.jpg) ![Bayliss XL Autovent - Automatic Greenhouse Window Opener - Temperature Sensitive Solar Vent Opener - Image 2](https://m.media-amazon.com/images/I/81SpjrgSbbL.jpg) ![Bayliss XL Autovent - Automatic Greenhouse Window Opener - Temperature Sensitive Solar Vent Opener - Image 3](https://m.media-amazon.com/images/I/71a4nUFGu7L.jpg) ![Bayliss XL Autovent - Automatic Greenhouse Window Opener - Temperature Sensitive Solar Vent Opener - Image 4](https://m.media-amazon.com/images/I/71-+SJB9rdL.jpg) ![Bayliss XL Autovent - Automatic Greenhouse Window Opener - Temperature Sensitive Solar Vent Opener - Image 5](https://m.media-amazon.com/images/I/71HSN4wXFeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works good so far *by M***W on May 22, 2017* I built a custom greenhouse with a wood frame, and needed a way to automatically open a window for ventilation.
