As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
Ordered 2 of them. One been working fine for a few weeks. The other one was dead on arrival. Complete short on the input. Removed input cap and it checked OK. The LM2596 IC was an input short.

Easy to Use
Easy to hook up and adjust. Potentiometer is touchy but you can get almost any voltage setting you want. I am running a ESP8266 from three Lithium Ion batteries. 12.3 volts in set to 5.1 volts out.

I ordered 3 and all 3 did not work. The feedback resistor to ground needs to be 1000 ohms not the 330 ohms installed. With the 1k resistor as suggested by the LM2596 manufacturer, it works fine, but you can waste a day finding the problem.

Saw a cold solder joint on regulator chip
I received one of these that was intermittent, and I found a cold solder joint on one of the pins of the regulator chip. If yours isnt working, use a pointed tool to see if you can lift any of the pins off its pad. Its hard to get the iron tip in to fix it, but that fixed my problem. Otherwise, its a really handy converter at a good price.
Problem with Circuit Board
I have 3 of these same units which I have just found to be defective. There is no connection from Vout to the inside. I found I could get output by taking it from the top of the output capacitor. I do have an earlier one..slightly different that works fine?

Great voltage controller
I replaced the 10-turn pot with a regular pot on 3 leads, and built the whole thing into a box. I use these as remote controls for my Garden Train layout, and they do work wonderfully!
Stable for Raspberry Pi
Been working solid for about 2-3 months now. Powering a Raspberry Pi and Raspberry Pi 2 B+ with these guys. Adjusted voltage to about 5.18 volts and it barley drops below 5 volts, even with a 1 watt Wifi adapter. My Servos have there own LM2596 as well, all running from a 12Volt UPS Battery.
