isn't bad, I have it in a 60 gallon tank and it circles pretty smoothly in the water, but it's quite noisy so be aware that it's noisy and you have to deal with it. Overall it's worth the price I think because it's a cheap product. ok its been almost 45 days since i bought this wave generator and it has stopped working, the fan is on but there is no water circulation. He literally does nothing. I have to remove it from the tank. I will upload 2 photos when it is off and a video when it is on, you can see for yourself.
