All five operate properly and tested with a couple 12VDC adapters plus a 9VDC; all came fully assembled plus appears to be a quality product (e.g. board, parts, solder joints). Also, measured with a digital multimeter and determined 3.3v exact from all but 5v for three (with two reading 4.96v) on the higher voltage pins. Therefore, all five are perfect for my purposes. As pictured, I powered microcontrollers via breadboard, header pins, and USB (output-only) successfully. I would repurchase again from this supplier. (Note: the recommended input range is 7 to 12 volts DC; I also tested with a 5VDC adapter and measured 3.3v but only 4.6v for the greater voltage output pins, which isn't surprising since some regulator loss is expected)

Immediately put each one on a breadboard to check output voltages. All 5 tested OK on 3.3v & 5v, LED illumination & push ON push OFF switch operation (see photo). Deducting 1 star for packaging however. Several modules had (slightly) bent pins due to the foam upon which they are "mounted" being a few millimeters smaller than it should be to accurately house & protect the pins. With a small needle nose pliers, I got them straight, without breakage & then had them properly inserted in the breadboard for testing. DEFINITELY get these, check the pins, & test outputs when they arrive.

It's a power supply, right? How complex could it be? I didn't see any reason these should be expensive, so I was glad to find a cheap five pack for a class I'm teaching. I've got other HiLetGo stuff; it's fine. It's not cheap if it blows out a couple microcontrollers and costs a few hours of debugging. On one, the 3.3 output is 2.8 (enough to cost hours of debugging embedded wifi). The 5v is 7.8v. Another let out the magic smoke before I had time to say, "wow, 10v instead of 5?!". On two others (so far) the same failure mode - but two lasted 30-60 seconds. Right now I have one that - works? I'm not sure I'm ever going to plug it in to anything and feel safe, ever, though. This is using verified and reliable power supplies putting out a consistent 12v for input. So yeah. It's not cheap if it destroys a few hours and fifty bucks worth of equipment. Not pictured: smoke drifting over my multimeter.

These seem very sturdy and because they are HiLetgo, I trust that the electronics are safe and good quality. They attach well to the breadboard and don't take up much space. They are versatile, as you can have either 5V, 3.3V or both fed to the breadboard. They also have additional power pins that you can use without the breadboard. It's very handy to have the power switch, so you can just power things off right at the breadboard. The packaging is lacking some as some of the pins were bent when it arrived. I straightened them out and things are still working. It is a little worrisome that this may have created a weakness that will cause problems later on. The only disappointment I've had is that it consumes part of the power. I should have realized this. It turns out that I need 7.5V coming in to get a full 5V of output. After switching to a better power supply, I'm fully satisfied. I'd recommend this highly.

The five HiLetgo 3.3V / 5V Power Supply Modules seem to be pretty good for the price. One shipped loose and the other four had to be snapped apart. Each one broke cleanly form its mate. The header pins on the loose unit had to be straightened to fit into the breadboard. The other four were fine. A visual inspection of the modules indicated that the workmanship was quite good. The surface mount parts aligned well with the pads. The solder flux was left behind on the header pins. Not a big deal. As for accuracy, here's what my antique but trustworthy Fluke 77 multimeter yielded: 4.98/3.27, 5.00/3.29, 4.95/3.29, 5.04/3.30, 4.92/3.32. These numbers were obtained with 12 volts DC on the input and no loads on the outputs. Once I have a project put together, I'll reassess these units as used and update if there are any notable changes. In the meantime, I think five stars is a fair rating.
