A fantastic regulator! Performs well, stable and easy to service. The Venturi lever gets a little gritty if you shore dive, because AL's tolerances are so narrow for those two plastic parts. But easy to wash out with a minor disassembly.The Leg3nd Elite is my primary go-to reg these days and it has been since I bought it a couple of years ago.
But since this thread is titled "Opinion please", IMO the accolades for the AL Elite DO NOT apply to the Leg3nd MBS. An expensive reg that conflates two entirely separate functions and calls it a "Master Breathing System" is an insult to divers.
