## Customer Reviews

### ⭐⭐⭐ 







  
  
    not useful
  

*by C***1 on Reviewed in the United States on March 4, 2019*

instructions are not clear and has very low output

### ⭐⭐⭐ 







  
  
    Good for electronics newbies
  

*by O***H on Reviewed in the United States on December 16, 2018*

The only complain I have about this product is that the included transformer is complete garbage, I can't pull even 0.5amps from it without having it heat up a lot and start making noise. I'm  giving it 3 stars because you get a lot of parts and even a laser cut frame for a very low price. Despite the fact that the transformer is cheap, it works, and you can use this power supply for small projects without any issue.

*by A***R on Reviewed in Canada on July 6, 2019*

The title says that it runs on 110V but the unit requires 220V as seen in the details. I have 110V and can only get a max of ~5.5VDC output. I'm giving it 2 stars because you get a cheap little power source that's fun to build for your bench but it was advertised inaccurately.
