Have to agree with this. I had the original AI adapter (metal) and it lasted for years (until a propane bottle fell off a table and landed on a nozzle, so not really its fault).
Then went through two of the new plastic ones (one red, one tan) in as many years through normal usage. Horribly disappointed by them.
So I got a Madbull one and it's in its 2nd year now and I'm happy again. No damage to the adapter NOR the fill valves.
