-All I wanted was a heated foot bath. I did not want a massager. This is great quality and great value at the price point for what I wanted.- It heats well. Once it reaches the "set" temperature (i.e., the temperature you set it at), it turns off the heater until the water in the footbath goes down by three degrees, and then the heater turns on again, & repeat. I would prefer two degrees. But that is just a minor preference.- You need to fill it with warm/hot water before you use it, which I have no problem with. If you put in cold/cool water it will take forever to heat up............but it is not intended for that. I use my hand to gauge the temperature of the water coming out of my faucet as I fill the footbath up.- I DO like that the removeable support does NOT have to be screwed in (support shown in the red circle). I saw some footbaths that used a screw to secure the support, but this one does not use a screw. It folds up to install into a notch under the "lid" of the footbath, and folds down to collapse the footbath. I like this feature.- The green lines in the photo point towards the two blue ovals where the bubbles come out. The bubbles are intended to circulate the water. This aids in dispersing the heat from the heater. The heater is near your toes and is the white raised item just behind the support circled in red. Don't expect a "massage" from these bubbles....again, they are only to circulate the water so the heated water does not stay only near your toes. But they do make a pleasant "babbling brook" sound while you relax!- In terms of the size of the footbath: To give you an idea of the size, I have men’s size 12 feet and if I move my toes all the way forward I have 3 inches of room between my heel and the back edge of the footbath. So, plenty of room.- I did see some footbaths that the sides are so high and the top opening so small that people complained about it. When I have my feet in the bath I don't feel that my legs or shins are constrained in any way. So this is another plus!- The only negative is on the bottom of the footbath; there are four "feet". Two feet are plastic and two feet are rubber (see photo with purple circles). We have a light colored bathroom counter and if I drag the footbath over the counter the rubber feet leave a faint black mark. This was able to be cleaned off however. This is so minor that I just make sure to pick the footbath straight up after I have filled it with water. Not a big deal, but this would be an item for the manufacturer to improve. The two rubber feet DO keep the footbath from sliding when you put your feet in/out, so the rubber feet do serve a purpose. This is very minor, so no issue.- The two rows of rollers do not move on their own (four on each side). If you want to massage the bottom of your feet you need to move your feet back and forth over the rollers. The rollers DO rotate when you move your feet. But again, all I wanted was a heated footbath, not a massager.- Max temperature is 118 degrees F. But I keep mine at 112 degrees, so this is OK with me.- It also has a timer that you can set in 10 minute increments (10 min to 60 minutes). I use the footbath for 40 minutes. So this is great for me.- Would I buy it again? Yes. It is a great footbath and value!
