Review (4/5): Great product, it does what I need it to do
I had read other reviews that complained about the bubbles and vibration not being strong enough. I was surprised that the vibration and bubbles were stronger than I expected. However, I didn't care about that, the main thing I needed was for the water to stay hot, and it does. As others have said, you have to turn the heat off periodically, or it gets too hot. I did not mind that.
The main thing I didn't like about it was that the bottom is all nubby. I have a very sore foot, and it was painful for me. I removed the rollers, but still can't rest my food on the bottom.
