When I needed to buy a foot spa, I really just bought the first one I found because I really didn't know what I wanted. I saw that this one was not just for soaking but had a heat and massage setting, so I thought that work well.
I am not totally impressed by it because I guess I expected the warm water I put into it would stay warm longer and that the massage would give me a little more relief. But maybe that's what all foot spas with heat and massage do, I just was looking for more.
If you want a foot spa to give your feet a good soaking, or if your doctor recommends you get one to use for therapy for foot problems such as a podiatrist, then the Homedics Massaging Foot Spa would be sufficient for you. If not, then look around.
