Query: disappointed...

After thoroughly researching and reviewing foot spas, I decided on this one by Dr Scholl's. It is a good size (both my husband and I use it), not too noisy, and we like that it has the option to be used cordless. However, it does not have a heater, so the water gets cold extremely fast. I have used VERY hot water and it is cold in less than 15 minutes. We were also disappointed that the rollers are so small, they are manual and you can barely feel them. If you use the gel pads, it is hard to keep them just right over the holes for the bubbles to come through. So it is an ok spa, but we're going to keep looking for a better one!
