This is so awesome!! You have to have patience...dont give up as it is extremely sensitive to where its placed. I have more pics but the app only allows 1 photo and I have to go full site but sadly you are always directed back to app automatically. ANYWAY....
A little bird was in this this morning and I have photos of the pie dish moved only slightly and it would respond very differently in a fraction of movement. But it went super high on first filling of water so Im not sure of the bad results. You have to move it and the solar stuff on top sensitive to amounts of water too. I noticed it wanted to be on the chair which was uneven but still went high. It has little suction cups to hold it down. I filled to the rim and saw that even if water was on top at one part it still worked well. I have only the cover patio. In full sun this will be going all the time. The birds love it so I love it. Great for my small space! Great price and no huge fountain to maintain and move!
