I liked the price, I liked the ease of installation, and I liked the simplicity of using these openers! I am a hobby gardener who is experimenting with Aquaponics and other growing methods. One important part of having a greenhouse is control of temperature. These openers allow me to open the roof vents a full 12 inches and I can vary almost on an inch-by-inch basis to stay within a 10 to 15-degree temperature range. Simple, easy to install, and at a reasonable price would sum up my review of these openers.
