Yes, I have one. It has a linear actuator arm (much more secure than a draw-string type.) Unfortunately I bought it online from an unreliable person that sells many of these. It is made of cheap components from China. The wiring didn't hold up (it's corroded the whole way through) and the photocell broke twice now. Yes, they make them, but best luck getting one with a better return policy than the one I got! The person I got it from is
mrinnovation2008 on ebay. In theory it's a great pophole, but the components didn't withstand being outdoors! Also, do you live in a sunny area? If the answer's no, you might consider running some underground cable. You could even do low-voltage by adding a transformer and stepping it down to 12v. Since the solar popholes are already designed for 12v, this would be really easy. Also, low voltage wiring is very easy to install, and you would still have the option of running it on solar in the summer.
