## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Excellent little power supply
  

*by D***S on Reviewed in the United Kingdom on 25 June 2022*

Great power supply and does exactly what I need, be aware it doesn’t contain any leads I already have a load of them but just bear that in mind. If you haven’t used a bench power supply before do a bit of research on YouTube etc the instruction manual is good but very concise.All in all very happy with it.
