Cute little fountain. My bird bath is entirely in the shade and it squirts up 8". If you put it in your bird bath, it will empty it in 30 minutes. Great entertainment.

Ex Output:
positive


Ex Input:
I would give it no stars. Worst stapler I have ever purchased. You have to push down several times to get it to staple, have the time it messes up and you have to remove staple and re-staple pages.

Ex Output:

negative
