Have tested all boards as shown in the picture with different input votages, however, one of the board's IC gets really hot, and doesn't oscillate, while others perform well as expected. Anyway, hope they will last when used properly for the price, for my 3D printed portable 3W LED desk lamp, as well as a supercapacitor high power LED flashlight project.

Just testing one from this package, it works just fine. I use it to supply stable power for a TFT display, Output is a nice stable 3.25 volts.
