Delivery was very fast. The product corresponds to the description. Quality is very good. The module works excellent and reliable. The output voltage remains constant even when the load changes. Have bought and processed these modules several times. To date, I have never had any problems or failures. Am very satisfied with this product. I will be buying more of these modules in the future. I can highly recommend a purchase.

Great unit. Very easy to adjust voltage with built in 7 segment display. Only improvement would be to add a 5.5mm x2.0mm(or 2.5mm) on the input side to allow connection to a commonly available ac wall adapter.

This product performs as expected. It accurately shows either input or output voltage, and provides good regulation even with changing current load.
