Definitely worth the money. It works good, just wish it would be possible to ad some sort of battery pack to it so the fountain could keep going for an hour or two when it gets cloudy.
The solar pump I bought about 6 month ago works without any problems in our pond. However, a nice string of water is only visible at the full sun. Depending on your water quality (algae) you have sometimes clean the nozzle. DIY-Upgrade: I have attached a piece of mosquito net / fly screen with thumbtacks on the bottom to prevent the clogging of the pump. Furthermore, I have attached a small anchor (fishing line + stone), to avoid that the pump swim across the whole pond. Good product for the price!
