I got one of these this summer and I love it! It works great and works best, the spray being the highest when the sun is overhead. A surprise benefit was that birds love it! Hummingbirds will flit thru the spray to play and wash. I have mine in a large basin and put a stick across so larger birds like robins could bathe themselves standing in the spray.
Several nozzles come with it for different spray patterns. Very easy to assemble and does not need batteries. The pump is quite strong. The spray makes a pleasant sound for you to enjoy when outside in the garden. Well, it's November here on the west coast and the time has arrived to bring it in and clean it up for winter storage before the freezing weather comes.
