Full listing title: HBS24-12T Digital Smart Instant Hot Water Recirculating Pump Kit Built-in Thermostat, Timer, Digital Screen, Extremely Quiet, Under Sink Recirculation System
Rated from the listing's specs, no buyer reviews yet
What it's made for: hot water at the far tap without the wait.
Two recirculation pumps close to it on our rating, each with a dated price.
What it has going for it
Recirculation, timer. It moves hot water to the far fixture before you open it, so you stop running a gallon down the drain while you wait. A timer keeps it from running all night.
Return line: if your house has one, the pump sits on it and moves hot water around the loop; the timer keeps it to the hours you shower; the thermostat stops it once the loop is warm, per the listing.
Crossover valve: without a return line, a valve under the far sink sends the cooled water back through the cold pipe. The cold tap runs lukewarm for a moment; that's the trade-off.
The seller states, word for word, in the PROZRTED HBS24-12T Recirculating Pump listing:
Features a digital screen for visible operation, a built-in thermostat, a built-in check valve, and a digital timer.
Designed for installation under the farthest faucet from the water heater in each loop.
Smart constant temperature mode and manual mode.

Our take
The PROZRTED HBS24-12T Recirculating Pump is about a timer and a thermostat, and it doesn't pretend to be more. No buyer reviews yet, so this PROZRTED recirculation pump has to win you over on paper. Our main reservation: a recirculation loop needs a return line or a crossover valve, which is extra plumbing. We'd pick it if you wait at the far bathroom sink for the water to warm up; otherwise, put it next to the PROZRTED HBS24-12E Recirculating Pump first.
Before you order the PROZRTED HBS24-12T Recirculating Pump, check your model number: it is listed for specific models, and fit is model-specific.
Not every tankless takes a recirculation pump the same way; some need a minimum flow, some have a built-in mode. Check your manual first.
A dedicated return pipe or a crossover valve under the far sink closes the loop. Ask which one this pump expects.
Use the timer so it only runs around shower times.
