## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Don't know how they make it for the price
  

*by A***R on Reviewed in the United Kingdom 🇬🇧 on 2 January 2023*

It's a bench PSU. It acts like a bench PSU should. It's overkill for a tinkerer such as myself, but it is really good for its purpose.

### ⭐⭐⭐⭐⭐ 







  
  
    Seems great
  

*by L***H on Reviewed in the United Kingdom 🇬🇧 on 24 November 2022*

I will note that I have only just got this today but I must admit I am pleased how much tech has moved on since I purchased my last switching bench supply.The screen is bright and clear, there a loads of options and the build quality looks really good.There are big heatsinks inside and an sort of semi intelligent fan which appears to be RPM based on the current load. I guess it'd make more sense for it to be temperature based but perhaps not!I'm sure this will make future electronic jobs and repairs a joy.

### ⭐⭐⭐⭐⭐ 







  
  
    Top-class programmable power supply, so good I bought two!
  

*by E***O on Reviewed in the United Kingdom 🇬🇧 on 17 November 2022*

Rarely do I use the term "outstanding" but we'll deserved IMHO given the price and the enormous amount of features packed in to the excellent power supply.The programmable voltage/current profiles are singularly useful being able to quickly switch between common 3v3 and 5v0, 1.8v limited to 20mA for quick testing of LEDS.
