    Product corresponds to the description. Processing and quality are very good. Have this product, already purchased several times and processed. Works excellent, everything runs without problems. Modifying the circuit is very simple. I can highly recommend the purchase.

    Has good solder job on the circuit board and good calibration of measurement readings. Comes in an sealed antistatic bag. I'm using this adjustable module to power LEDs on DIY projects. It does the job nicely and is very accurate but it is not able to output higher voltage than the input voltage. It's 3 digit LED display is a nice touch. The output voltage can be adjusted by adjusting the potentiometer. It works perfectly without heating. I ordered two more. I recommend it to anyone who wants to produce a stable lower DC voltage from a high DC voltage.

    I already used one one similar device. It is well built, the voltage meter is correct, the functionality is much more than one can expect for this price. The shipment was reasonable.

    This is a step DOWN only unit, not a "DC-DC step up/down voltage converter" as the product spec states. As such it works ok, but please correct the product description accordingly. Minus one point for that.

    Used on my 3d printer to power up a 12v led strip from a 24v power supply. I printed a case for it, perfect addition
