Works great, provides stable output
I paired one of these with a Turbomax reverse indirect water tank about 1.5 months ago. It's been working great and provides pretty stable temperature output.
It does appear to adjust pretty slowly when only a small bathroom faucet is running (as would be expected since the spec'd min flow is 1gpm), but the comfort impact is negligible.
