Query: Nice unit

This is a nice little unit and I really like the heating function and attachments. One thing to be aware of, however, which I found a little disappointing -- you can't use any of the extra attachments with the heating function. The round heating plate is nice, but it would have been wonderful to be able to get heat with the facial massage or deep massage attachments, too.
