Nice small, reliable buck converters
Good value for money buck converters, had them running 24/7 and they output the correct voltage continuously when set with the potentiometer. Very small form factor would recommend.

Compact solution to drop 24v to 12v/5v for my Noctua Upgrade
Worked great when upgrading the fans on my Ender 3 V2. Take time to dial in the required voltage correctly. Twin output is useful if running more than one fan off the Buck or in my case sending the 12v output off to a Micro USB buck to power a Raspberry Pi. It states an input voltage of 23v but working fine with the 24v input on my printer. All 5 working great, no duds.

Does the job!
Does the job. Needed to step down 12v to 5v for an ESP32 project I was making. The pot on the first one "broke" -- or at least couldn't be set accurately. This could have been me winding it too far one way, but I don't think I put too much force on i.e. The second one was fine through the development and I wasn't particularly gently -- I'm sure it fell of the desk once or twice too! This one stayed the voltage, but I added some hot glue during final assembly of my project to be sure. I've not tested the remaining 3 boards.

They just don't work
The first thing I did was test them. I was looking for 15v in with 4v out. Two popped immediately and got very hot. The other three worked long enough for me to set them to 4v using my multimeter to check the output voltage. However, by the time I came to try them with a load they weren't outputting anything. Avoid.

Ideal to set down from 24 volts to 12 volts.
Used one of these to reduce voltage from 24 volts to 12 volts on my 3d printer to run a different fan. Works well. It was also possible to find a 3d printed case on a well known website for stl files which worked perfectly. Good value for money.

not a good regulator
I recently purchased the MP1584EN Ultra Small DC-DC 3A Power Step-Down Adjustable Module, and I was disappointed with its performance. While it is compact and easy to wire up, I found the output voltage regulation to be inconsistent, especially under load. The module struggled to maintain stable voltage (24v in with 12v out @ 150ma), the voltage fluctuated between 9 - 12v, causing issues with my sensitive electronics. As the quoted value of 3amp is not quite up to scratch. . BTW I did try all 5 units with similar results. Overall, I wouldn’t recommend this module for critical applications, as it failed to deliver reliable performance

It works
I am using this as a fan speed controller because with other PWM controllers, the fan is still noisy and additionally there is a high-pitch humming. But not with this! Now it is silent like the snowfall and absolutely worth it!

Step down
Excellent device. Easy to setup!!

Levererar inte ut rätt spänning.
5 av 5st defekta vid leverans, någon saknade komponenter, ingen levererade utspänning över 1.9V vid 12V in. Testat liknande från annan säljare med samma ic men lite annorlunda layout på PCB där alla fungerat ok. Och fungerar efter flera år av användande. Inte värt att returnera, kasseras med varning till andra att köpa dessa. Besviken på att Amazon säljer så usla produkter.

Dobry Regulator napięcia DC
Moduł step down działa bez zarzutu zgodnie z opisem. Trzeba jedynie uważać przy regulacji napięcia wyjściowego, bo śruba regulująca jest bardzo czuła. Generalnie polecam produkt

Parfait
Très bien. Je ne prend jamais les modèles avec vise de réglage de tension, je n aime pas ça et généralement (de mon expérience, peut être bourin) ça casse ou se dérègle de peur. La, aucun souci, fonctionne très bien, livraison dès le lendemain. Je les utilise pour des esp32-s2mini, en 5v sur vbus (je le dis puisque j ai vu ici et là, des personnes qui posaient la question si on pouvait les alimenté en 5v donc, voilà, je le dis ici aussi puisque ça doit être un grand secret pour certains qui lâche rien et relance ces povres personnes qui demande désespérément si c'est possible et sur quel pin !!!). Moi je règle légèrement sous les 5v a 4.8v... Petit format, pratique et parfait pour mon usage 👍 Et pour pas les grillés, faut respecter leur capacité , les polarités, sens du courant et... Les tensions 😁 Ou alors, ça arrive, problème de fabrication... La, la série que j ai eu, fonctionne très bien. Faut peut-être en profiter et commander un camion... 🤔 Non j suis pas vrp de ce vendeur 🤣 Bref, ça fonctionne, allé y si vous en avez besoin 👍 (et penser à régler sa tension avant de branché sa sortie... Moi il était réglé un peu au dessus de 10v. Amusez vous bien 👋
