I tested all 5 power supplies and all were within 1% of the nominal voltages. They all fit my breadboards perfectly. Quite handy while prototyping, whether it's a 5v or a 3.3v project.

The way they packaged them was kinda half a**ed. One of them actually came broken and i could use it.

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)
