It hurt. The pressure release didn’t work. Dropped from my end table and broke. Cheaply made. Would not buy again.

I received my product and submitted a complaint that the blue foam strip had tire tracks on it as if it was run over by a truck. I even sent a picture. Their support apologized and said that each product is carefully scrutinized before sending to customers. After several follow ups via email, I got my replacement almost three weeks later…and the new blue foam strip I got still had BLACK TIRE TRACKS AGAIN! (Rolls eyes)
Works great. The suction is pretty intense even one level 1.
