Handy for small microcontroller projects
I was taking apart 5v power adapters when I needed a 120v to 5v power source for my small projects. This saves some time, is much cleaner, circuit-board mountable, and only costs a little more. The data sheet suggests a putting protective filtering components on the 120v side of the supply.

Tiny and functioning well
Bought less than a month and tried one with a laser diode works out pretty well so far. Will see how long it goes. Based on the light condition, it’s pretty steady means the output voltage is steady as well.

Miniature size: Solid 12V regulation
All three modules work. Each outputs exactly 12V from 0mA to full load (tested at 50mA full for my project).Each runs warm only, and there's no audible switching noise. I have a 100nF cap. on the output for filtering out any high frequency noise. As the manufacturer recommended for input protection, I put a safety(X2) cap. in parallel with a transient voltage suppressor across the 120VAC mains input. Also, I added a fusible resistor. Input protection may not be necessary, but I did just because I had these components.Anyway, so far I impressed with the SMPS module. It delivers a solid 12VDC, is efficient and isolated from mains AC.I have recommend these modules for those looking for a very small, 120VAC to 12VDC power supply.

Not perf board complaint
The pins don't fit in a standard perf board. I'm not sure how you are supposed to use it. The only way is to solder wires straight to the pins. Not good if you ask me. Other than that it seems to work well.

Works Great!
Works as advertised. Great little AC to DC converter. Used this to power a little DC motor.

Great for powering ioT devices
These units are great for powering ioT projects. They are compact and can be built into the device enclosure instead of having to use a 5V wall wart and a USB cable. Voltage output is stable and they run cool. My applications have been at 500ma or less.

Not breadboard friendly
If you're planning to use these on a solderable or standard breadboard, be aware that the module ac pins have a 5mm separation and will not straddle the center 0.3" dip section. Oddly, some dimensions are close to 0.1" spacing, whereas some are not. By bending the pins severely, it can be jammed in to mount horizontally.
