Does anyone have experience with dental handpiece online?

I have one. It is overpriced and sells for $250 online. It is almost a replica of Vaporbrothers' original carburetor, and it costs $100.
On the positive side, than Vaporbrothers vaporizer, the screen is easier to change (though you can avoid in the dishwasher with cascade detergent put their hands in the dishwasher change VB screen).
On the negative side, silver surfers' craft and materials are a bit cheap (at least on the side I have, it has a plastic base).
