It goes up to about 7hg before it automatically releases pressure to avoid going above it. That’s the ceiling in dynamic mode. And I think it may go a little higher in static mode.
It pulsates in dynamic mode and you can set the max HG that it will pull up to and then it releases which is adjusted by the speed at which you want the device to operate within the particular exercises parameters.
And in fixed/static mode the only time it makes a noise is when it’s building up to your pressure requirement, and then intermittently, to maintain that pressure which is all dependent on how good of a seal you have.
I really like the device, obviously having bought it twice now and then subsequently sold, or selling.
The only con other than the price is, in my opinion, it’s pretty loud. Others have disagreed but for me I constantly want to smother it with a pillow.
