so far, appears less likely to fall apart in normal use vs the right angle flow controls

still being sold at popular soaring supply houses. The right angle jobs seem to last about three wave camps. Mine broke on the ground, others have been less fortunate. The plastic flowmeter housing generally breaks just above the needle valve.
