    Prompt shipping, works good. Used it to run a project off of battery power. The adjustment screws are labeled on the reverse side of the board

    These boards are good but the one we received had a manufacturing defect. It failed after running for a week due to a loose solder joint, but Jacob offered a full refund upon returning it. An excellent seller, buy with total confidence

  • Poorly packaged.

    This item was mailed in a polybag and obviously crushed in transit. Upon further inspection, one heat sink was separated from the board at some point before shipping. The heat sink was damaged, but still re-applied to the board with the same gunk used to attach a CPU to a computer motherboard. They used too much gunk and the heat sink slid beyond the perimeter of the PCB and dried. It is now sticking out beyond the perimeter of the PCB and slightly off the chip it's supposed to protect. In addition, one potentiometer was bent in transit. I don't trust that it will adjust anything when power is applied. The unit arrived without any directions or even a Spec Sheet, no paperwork whatsoever. It was thrown in a bag and mailed to me. That's it.

  • DOA

    Unit did not work. No output, no adjustments. Used with 14V input. Cheap enough to not bother returning. Others have had no problems, I might try another one

  • Good product

    Works Great. I swapped the caps for a combination of ceramic and poly electrolytic for higher efficiency
