Are you referring to their double action pump ? (pushing air on both up and down strokes)
I've been testing the Bravo double action SUP pump for the past 3 months.
Pros :
Faster to pump to about 7psi
The attached and recessed gauge in the top is a great idea
You can deflate (remove more air than pushing out alone) meaning you can make the SUP smaller when you're traveling
Cons :
after about 7psi you will want to remove the bung and make it single action,
but with only this small bung removed there isn't enough air coming in so you find your self fighting the pump on every up stroke and wasting energy
I find this is a major flaw and I won't be ordering any of these pumps.
