## Customer Reviews

### ⭐ 







  
  
    Chip with ground-off markings, different from picture
  

*by T***N on Reviewed in the United States on September 27, 2019*

The units I received had chips with ground off markings where the MP1584EN is supposed to be, i.e., some clone or lower-performing chip. The inductor was different from the one pictured (lower inductance if my interpretation is correct). Overall, it's not what is pictured. Returned.

    ABSOLUTE JUNK! Find another option
  

*by A***R on Reviewed in the United States on September 24, 2019*

First one I opened did not work. Second one works, but does not adjust properly. Third one worked, and will not adjust to 5.0V. Would not recommend product. Tested on a calibrated Fluke multimeter.Update: tuned via multimeter, disconnected and hooked to an arduino...it fried the Arduino and had an output of over 10v with no change to the pot. ABSOLUTE JUNK!!

### ⭐⭐⭐⭐⭐ 







  
  
    These things work great, and have a small footprint
  

*by M***E on Reviewed in the United States on July 25, 2018*

These things work great, and have a small footprint.  Just be sure to NEVER reverse the polarity of the input, it blew up almost instantly when I connected them for a second.
