BEST Fittings do a Push Button Bleed Valve Upgrade for MDE Valves and Charging Kits (it replaces the bleed screw). Anyone on here have one fitted to a bulk HPA cylinder - any benefits?

Recently bought the 500cc Day Tripper bottle from Best Fittings, which is ideal for my uses, it has a push button bleed valve. The benefit seems to be very rapid dumping of air and presumably fast closure of valve on the airgun. The rapid release of air gives quite a loud pop (unlike the relatively slow release of a bleed screw).

The standard bleed screw on a bulk HPA cylinder can be used to 'soften' (fractional bleed) the inrush to an Airgun cylinder, fitting a push button bleed takes away that optional fine control.
