Some mention that it has a low flow monitoring, temperature readout, and colored LED to indicate, that it's accurate, and the enclosure feels solid.

Good Heater
Just put it in my tank, seems to work great but taking a star off because the top lever is broken. Didn’t notice until I put it in the tank and doesn’t affect the functionality at all so planning on keeping it, but still frustrating.
