Not great, but okay for the price.
Not great, but does move the water.  Can only get massage action on one side of your body unless you physically turn around in the tub. I guess if want a full whirlpool you just have to buy a real jacuzzi And pay the $1500 price tag plus installation, but this feels okay.  The motor was not loud as some others have complained about, but produces a humming noise that I find kind of relaxing.
