great - here's a modification 5 out of 5 stars

Reviewer: from MONTESANO, WA USA

You can unsolder and remove the onboard pot and wire in a 10K linear pot if you want to be able to adjust the voltage from a front panel!

Makes a great solar charge regulator. 5 out of 5 stars

Reviewer: from GARFIELD, NJ USA

This regulator can be used for solar powered battery charging. Just connect your solar panel to the input, then adjust the output voltage to 13.7 volts. Now you can charge a 12 volt Sealed lead-acid battery without fear of over charging.
These buck regulators have a neat feature - they put out more current than is drawn at the input!

DCC-3 and PM-233 5 out of 5 stars

Reviewer: from Cololrado

With these 2 items, a wall wart, and a small utility box, you can easily build a variable voltage supply which can replace all those batteries in portable radios, etc. Also nice to be able to read both voltage and current without fumbling for test equipment.

Very useful, cool and efficient 5 out of 5 stars

Reviewer: from Toronto, Canada

I agree with all the other comments. Install the 10k replacement front panel pot for added usefulness.

The LM2596 is NOT the real thing! 1 out of 5 stars

Reviewer: from Chicago IL

Bought two and discovered that the LM2596 device is not a LM2596 at all but some sort of a chinese counterfeit device. The switching freq at the catch diode is ~50Khz and not the 150KHz as specified in the National data sheet.

Yes, the board nominally works, but I have no confidence in the actual ratings of the regulator.
