The vibration and heat are great.
It did not smell bad when it arrived.  Overall the value for my money is pretty good.  The ease of use is lacking.  The sort of sharp plastic edge around the top cuts in, or rather digs in, to my ankles when me feet are soaking.  If there was a soft piece of foam that could be removed when not in use, that would be wonderful.  I wish the attachments could mobile but
