Not even a drop came out in the sun. There are only two heads in the box and not 5 as described. But what good are they if it doesn't work.

It works, but only if full sun the water goes farther than the edge of the solar cell. Not very practical, since a fish pond needs at least some partial shade. The item arrived without any manual.

Immediate exposure to the sun and the filter underneath (the grooves and the sponge should be spotless) are necessary for it to function perfectly. The stick reaches 80 centimeters only with the above conditions, so you need to clean it every two days.

Plastic and fake. It doesn't work at all on cloudy days.
When I opened it in one corner, it was already cracked, but I thought it wasn't worth the trouble to send it back.
It worked for two weeks, the crack grew and suddenly it stopped spraying water even with sunlight.
