I've bought quite a few of these recently because I have a lot of birdbaths on my property that I want to fill.
The square design is great, because it allows you to mount the solar panel wherever you want away from the birdbath. This is perfect in case your birdbath doesn't get sun at some times of the day.
Comes with instructions and very simple to install.
Powerful pump shoots water up in air, and has several different nozzle attachments to change the spray pattern.
