Just installed the PROZRTED HBS XPH pump and wow – instant hot water is no longer a luxury! No more waiting ages for my shower to heat up. The built-in timer is a lifesaver for scheduling, though figuring out the programming took some trial and error (that light indicator situation? Not intuitive).

The pump itself is whisper-quiet – I literally have to touch it to confirm it's running. Heavy-duty brass construction feels premium, and installation was surprisingly smooth with all included parts... except for one user's nightmare leak scenario (yikes!). Mine held up fine though.

Two heads-ups: 1) That mysterious slot on the side? Still don't know its purpose – manual completely ignores it. 2) The price made me gulp, but considering the water savings and convenience, I'm calling it an investment.

PSA: Works ONLY with tank heaters (not tankless) and DO NOT run dry – the instructions emphasize this in scary bold letters for good reason.
