Go for it
I really like this unit.  It is big enough to accommodate my husband's size 11 feet without being too crowded.  The noise I'd say was as loud as I expected from something making bubbles and vibrating.  The heating element did keep the warm water I added warm - even over 15 minutes of use.  The little attachments are pretty worthless (scrubbers and brush) as they don't rotate and aren't situated at any useful angle, but I didn't buy this for those functions.  The rollers in the bottom don't roll/massage on their own - not a bad thing just a heads up.  Only reason it didn't get 5 stars is because I was hoping the vibration would be a little stronger and translate better through the bottom rollers.
