Works amazingly for such a small thing. It is so small, it is difficult to solder wires and you need a 1mm screwdriver to adjust. However, once adjusted it has very good input regulation ( see images). From 8.90 to 14.50V input the output changes only 1mV! The input must be at least 1.5V above the desired output for it to work. Adjusting to 3.3V is very touchy if you try to hit 3.30V exactly. I have not tested it for loads regulation or at high current yet.
