Bests & Worsts Reviews from Amazon

Picture is self-explanatory about the situation. Very noisy unit. Impossible to use at any setting except the lowest. They use low-quality air pump without decoupling it from the wood. So the whole noise transfers out. They think that by sticking some open-cell foam into the pump compartment, they will be able to dampen the sound. Well, Soundproofing 101 -- In order to stop vibration noise, you need to decouple the source from solid mediums! The makeshift box I made above was so that I could use it at the lowest setting! Those advertising this as "quiet" must have degraded hearing. You cannot sleep in the same room with this. It might be okay for noisy office spaces or spa rooms, but if your house is quiet, you will regret it. I have similar item from another seller. It is the same as well because Shenzen Tyloc/Rainbow company manufactures it (for $15), and everyone here sells it for $80!!! I am returning this and ordering a $25 unit. With a proper soundproofed box, it will work well for its purpose.
