I just got this little fountain a week ago. It's really powerful. I was surprised. It's so cute and I really enjoy it. I hope it continues to work for a few years. (If it only cost $10, I wouldn't mind if it lasted only one summer. For the price, I want it to last at least 3 years!)You should know (vendor states this) that this fountain will not operate on cloudy days or when the sun goes down because there is NO battery to store the sun's energy. As soon as the sun disappears, the fountain stops. That's fine with me because I bought it for my backyard birds. They won't mind if it stops now and then. They go to bed with the sun.The little suction cups are useless unless you have a glass or ceramic container. You also need a DEEP birdbath, or just buy a 20-30 gallon patio pond that's at least 28" in diameter and 6-8" deep. Why? because the fountain floats around the container if the suction cups fail to hold it in the center. The spray goes over the edge of the birdbath and the birdbath water is depleted in less than 45 minutes. That's why the fountain has suction cups--so you can fasten it in the center. My birdbath is wrought iron, so the suction cups won't work on the irregular surface. The bowl of my birdbath is 16" diameter and about 3.5" deep. The spray went everywhere except back into the birdbath as the fountain floated around the edges. I stopped that by tying the fountain to the center of the bowl. The perimeter of my birdbath has evenly spaced holes -- like lace. I used 2 pieces of the clear fishing line that came with the fountain to anchor the fountain in the center by tying it to opposite sides of the birdbath bowl with equal lengths of line. It still spewed water our of the basin unless until I removed the sprinkler head. Now, it shoots up a short stream (about 2")that does not throw water over the sides. I'm going to buy a black, 25-35 gallon patio pond and center the fountain in it. The spray heads should not throw the water over the edges of a 28"-diameter container as long as the fountain is secured to stay in the center of the water container. I wish there was an easy way to keep the fountain in the center without the fishing line. Otherwise, I like it so far.I have a deep basin birdbath and I was looking for a fountain that would not have wires running over the edge. There are a couple of different solar fountains on Amazon. I picked this one because of the reviews.It is small in size about Hand span width. The fountains heads are about a quarter sizes. There are 3 different ones and a cap one.As soon as I took it outside the pump turned on. I had to turn away from the sun. I am so mixed on it. As soon as I put it into the water the fountain turned on. I tried each fountain head and picked the one I liked. They shot up nicely about 10-15" depending on the sun strength and fountain head. It has a very delicate fountain sprinkle. It is not high powered but it does reach a good height. Since it floats around my birdbath I did not want the water getting too high and leaving the birdbath. For me it does not create the trickling sound it is very quiet.So when it works it is great. If any shadow casts over it, it turns off. There are little solar panels in a circle around the fountain; if any of them get covered it turns off. If slightly covered the strength decreases. This also includes the pedestal the fountain head sits on. So as it floats around and the pedestal casts a shadow on the base, the strength will decrease or turn off.The battery does not store power.I think this would be good for a shallow birdbath. There are suction cups on the bottom of the pump.For me it works for what I want. I wanted solar, no wires and under $50. This fit.
