Works perfectly, drops a 12v source to 7.5v source, with up to 3 amps output still, which is perfect for most Canon dSLR cameras if you wanted to make a DC source yourself for long term external battery use, like an external big lithium pack, such as used for late night long hour deep sky astrophotography with hours of long exposures time or for time lapse photography. I spliced it into a DC cable with a pair of strippers and tape!

I modified a garage door remote to use the car battery instead of its own. I used the Drok converter to step the voltage down from the 12V coming from the car battery to the 3V used by the remote. I installed a switch to the dash and wired it to the remote (now sitting inside the dash). The car now has a hard-wired garage door opener.
I have done this to several vehicles. Sometimes I use a universal remote. Sometimes I use the remote that comes with the garage door. I typically use the Drok converter. I can build a converter with a few Radio Shack components, but the Drok offering comes in a nice, waterproof, package. It saves me lots of time, and works really well every time. All in all, it's a great buy.
I'm not affiliated with Drok, nor was I paid or given a discount for this review.

First came DOA, shorted across the input. I was just lucky my power supply didn't die.
Second came working, I was using about 800ma (not even close to it's limit). A few minutes later a really acrid smell started emanating from my ATTiny. My hand brushed over it and it burned me, I pulled the power and started testing pieces of the board.
Everything was dead. The ATTiny, my sim module which was connected to it, even the LED I had hooked up to the indicator.
I got to the final culprit, this garbage regulator. It was outputting 12 VOLTS OUT from a 13 VOLT INPUT. And to make it clear this was the 3.7V model so it was out of range by 324 PERCENT. So my everything in the circuit designed to take 3.7V was turned into a hand warmer.
It's cheap for a reason.
Edit: I forgot to mention, in the original circuit it was running at 12V, I just didn't want to plug it back into my still working power supply so I used this cheaper one to test, even at 12V from the original supply the output was completely unregulated
