The basin holds about half a bucket of water (ie about 5l), and this covers the feet up to the lower edge of my ankle. Through the bubbling water also reaches to the ankle center. Since I have acquired to calm my ankle arthritis me a higher water level would have preferred, but it just seems to be enough so (I do not, unfortunately, not a heated pool with a higher water level is known).
It injects very little. Therefore, I have no hesitation to use it in the living room on a runner over laminate. The last few days I've used it several times a day for 30-60 minutes each, and find it quite enjoyable.
As others have noted, the noticeable effect of vibration massage is rather low. The air bubbles, however, are very pleasant. The noise level is within the scope. At first I felt the ground and the "massage-roll" as a very uncomfortable (hard and sharp), but after a few applications, I got used to it. How could accomplish with these targeted reflexology massage, however not obvious to me. The advertising seems misleading, for me, it was, however, not a reason to buy.
Magnets and infrared lighting, I think just for superfluous bells and whistles, but the latter makes at least visually a little ago. On the pedicure accessories together with rotary engine I could do without too happy. The pressure to be exerted before the engine turns, in my eyes is also too high. The fine line between "revolves not because switch is not yet closed" and "no longer turns, because resistance to strong," is hard to find and keep.
Conclusion: I use it like, relaxed and it also has a soothing effect on my ankle pain, but I would have raised pools (like without all the frills) preferred. But something seems also heated nowhere else to give ...
