I was very dissapointd with this item and have returned it, thankfully with Amazons 30 day limit and I have been refunded with no quibbles.
The first annoying thing about this item is that it came with a moulded Continental adapter. So this meant I would have had to buy another adapter.
The second thing was that I originally went looking for a Foot warmer as a present for my wife. When I say this item at very little extra cost for the massage option, I thought it was a bargain for a better modle. However, I was wrong. The massge unit is very hard and so would make keeping this on your feet for an evening uncomfortable.
I will be looking for an alternative that just warms the feet. If you specifically want a massage option, then this may work for you (I never even plugged it in because of the continental plug issue, so I cannot comment on the quaility of its massage), but dont make the mistake I did and think this is a foot wramer plus
