I've had two of them. The first konked out quickly. The results with
the second one were as disappointing as the first.
There is just not enough pressure or volume to clean deeply at all.
About all its good for is drying after you ultrasonic something. Even
at that water remains inside crowns etc. Plus its very awkward to
use, one hand controls the on/off and the nozzle is in a well which
Much better imho to spend the extra time with an ultrasonic which
gives you a few minutes to schmooze with the customer.
I had been contemplating the jewel jet pro but I don't see pressure
specs anywhere. If it doesn't get close to 60 lbs it'll be about as
useful as the smaller one.
