I grabbed this ROADTEC Solar Fountain Pump with a nice discount through Rank Booster and I like it a lot. I actually got a different one that was round and made especially for bird baths, but this one looked like it had some advantages over the other one, so I got this one, too. (I've been wanting to get a bird bath because I have lots of birds where I live, but I know that standing water can be a breeding ground for mosquitoes, which I also have lots of where I live.) And it seems nicely made, considering that even at full cost, the price is very reasonable. It's easy to assemble and comes with your choice of several tips so you can choose what your fountain spray looks like. This one has a more powerful pump and according to the listing, it's got a taller spray than the other, as well.
One thing to note, that is the same as the other one I have and that you may not figure out from the listing, is that it doesn't store solar energy like most solar yard lights do. It's powered directly by the sun through the solar panel, so if there's no sun or it's cloudy out, it won't be running. It only runs when there is sunlight hitting the solar panels. So I'll be making sure I have it set up in a spot in my yard where it's sunny most of the day.
So I'd recommend this if you have a small bird bath or pond and want to add a little fountain and circulate the water a bit. It's a really neat device!
