Review: Dont even skimp on voltage regulators or you will pay for it.. these are great!!! - Excellent adjustable buck style voltage regulators.. don't get hot, provide a soild voltage feed with raises and falls that stay within 1 to 2 hundredths a volt.. give a fairly clean output voltage (still need a LC filter if you want very clean wave forms) provides 0.6 to 23 volts from my testing.. able to pull a constant 3.5 amps off it at 16.8v without it getting hot 2.5amps at 20volts gets warm but ok... 3amps at 20v will cook the coil in about 20 minutes.. at 12v I was able to pull a solid 4.2a off it for 2 hours and the temp never got above 97F, 4.5a at 12v smoked it in 7 minutes... If you cook the coil on it it does NOT allow full voltage to pass through (I have had some buck regs fail and allow full voltage to pass through for a few seconds.. I killed two of these intentionally to make sure that when it failed no voltage pass through and on neither one did that happen and that makes me VERY HAPPY. A failure acts like a breaker, it fails it fails and circuit is instantly broken.. I tested this with a O-scope and it had 0ms of full voltage seep when it failed..) These are incredibly cheap and excellent quality.. over preform and stay dang steady.. These are without a doubt the best cost to preformance ratio bucks you can buy... Bucks are not a place to skimp and buy as cheap as possible BECAUSE a failure on a buck that is supplying constant regulated voltage to high dollar electronics and fail and allow unregulated voltage to seep by for even a 1ms can damage sensitive to voltage electronics and ruin your day and make you wish you wouldn't have saved that 30 cents per piece.
Review: Worked great in the beginning - It worked great when I tested one of them. So I permanently glued it to my setup. And now the potentiometer is not changing the voltage on 3 of them. I am pretty sure I didn’t turn it too far but who knows maybe I applied too much force. So just be gentle I guess. Giving it 1 star because the product was great when it worked. But didn’t even last a few seconds of adjustments. EDIT: I changed my mind. They are working really good now. Yeah the potentiometer can be finicky but it works. By trial and error you can get the right voltage. Just be careful to go really slow and gentle while changing voltage. Don’t push down too hard and turn slowly.

### ⭐⭐⭐⭐ Nice little board but just a little too finicky at the low end
*by S***N on February 21, 2020*

These may work really well for larger drops (12V to 3V?) but for my use of 5V to 3V the potentiometer is just way, way too finicky and nearly impossible to adjust with accuracy. The tiniest bump or turn and the output V can swing from 1V to 4V. I really wanted to like these little guys because the larger adjustables are just a bit too big for my use and these are a dream in terms of form factor and performance, but my use case is not sitting still in a box untouched or unbumped, and the little potentiometer screw here is just not solid and discrete enough for the low drop use case I needed them for. I'll be looking at other projects with a bigger drop to give them a better try in future.
