I’ve used them in one or two projects… they work great and are an amazing bargain at this price. I’ve got them dropping 17VDC to 5VDC to drive a Raspberry Pi Pico and about 150 WS2812B LEDs (not at full brightness… just a couple amps of current) and it works like a charm. The 5VDC level looks pretty smooth on a scope.
I take one star off because the mounting holes are not on a 0.100″ (2.54mm) grid spacing. This means you have to create some custom headers if you want to use this on a breadboard, and a custom part if you want to put it on your printed circuit board design. It’s not a deal-breaker, but just frustrating that whoever designed the board never thought “Hey… Maybe someone will want to plug this into a breadboard one day!”. On the bright side you can surface mount the part directly to a PCB. I am writing this review because I’m buying more of them, so they must be good! 🙂

Work well on the bench in buck mode even at 5V and 10Watt load from automotive input around 14V (alternator turning). useful.
