Defective item. The head fell  off
I bought this item last March 2023. I’ve noticed that as I continue to use it the vibration strength is decreasing. I disregard it until I’ve noticed that the other head is gettin loose and eventually fell off. I’m very disappointed d/t the item itself is very expensive. I called the Amazon for a replacement but it past the 60 day period refund policy.
