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.

The straight one you are showing appears to be the newer model from Aerox.. If so, it is the one that they tested to -50 degrees and is made of a much better material than the second one you showed.

When I had mine broke in half changing over to a mask at 23,000 ft, I was in a world of hurt. I got down ok, and there is a little story to that, but not for now.

I talked to Aerox and told them they about killed me with their cheap product that was supposed to be aviation grade. They responded telling me that the clear one is fine for WARM conditions in a cockpit, but their new thicker one was tested to -50, and a heavier material that would hold up fine in wave conditions.

IF YOU HAVE THE OLD CLEAR ONE, THROW IT AWAY, AND GET THE NEW ONE FROM THE DIFFERENT MATERIAL. Or better yet put in in your freezer, then pull it out and snap it like a twig so you will never be tempted to use it again.

GET THE NEW ONE THAT IS BETTER MATERIAL, LIKE THE FIRST PHOTO.

I was 10 minutes away from an eastern Lennie in my 1-26. Glad I was not higher when it failed.

It's unfortunate that the Aerox flow meters are now limited to 25K, as they used to have a scale to 30K. The flow meter that Dan advocated appears to be a better choice if planning on exceeding 25K.
