Well, since you asked...........I bought one of these 3 years ago.
https://www.songbirdgarden.com.... It works OK, but doesn't have a lot of force. But it's cute and doesn't seem to scare away the birds. It's in my shadier garden but mine kept floating to the shady side of the birdbath and would stop squirting. Also when water evaporates out of your birdbath, fountain will stick on the bottom. Kept having to walk out and top off water to keep it floating. But with adequate water level and full sun on the flat surface of the 'fountain' it works as advertised. Three years later, it is now down at our cabin birdbath an hour south of where we live, where the birdbath is in FULL sun until late in the evening.
