    Buck converter; I needed for a 12- 5V conversion. It does the job, after adjusting the trimmer. Recommended, would buy again.

    Great product lots of application

    Worked great for me and I haven't been all that nice to them. Watch your wire size and location and it's fine.

    Inexpensive and easy to use, but gets too hot if you need 1 amp or more

    Inexpensive and easy to use, but don't try to get anywhere close to the rated 3 amps. I set mine for 2.8v output driving a 1-ohm load (2.8 amps), and the entire PC board got too hot to touch within a couple minutes. I was afraid to leave it running as I'm sure the heat would have continued to increase until something fried. Also, at that setting it was only 64% efficient (over 12 watts in for less than 8 watts out). That's no where near the advertised 92%, which explains the heat problem. This board would probably be fine for less than 1 amp, but I would not recommend it for anything over that.

    The product is perfectly fine nothing wrong with it. If you know what you're doing. I order 6 of them they all work fine to me.

    Good Product. I highly recommend it.

    Great regulators

    These switching regulators run much cooler than linear voltage regulators and work great. Add a fan if the current is greater than 1/2 Ampere. They can handle about 3 A. if the input can furnish 3 Amperes.

    Works as indicated.

    I use this device to drop 5V USB output to 4.3V to emulate a lithium battery without issue.
