## Customer Reviews

### ⭐⭐⭐⭐⭐ Does the job
*by A***E on 6 October 2020*

Not much to say, it does the job intended. Good price & next day delivery.

### ⭐⭐⭐⭐⭐ Five Stars
*by K***F on 6 October 2015*

Genuine part, just the job

### ⭐ Part sold by Prime Electrical Group Ltd is NOT new
*by C***N on 27 July 2021*

There is no way the MCB I received sold by Prime Electrical Group Ltd is new. There are marks on it for starters, broken plastic around the lower terminal, and the terminal itself is bent upwards. These are pretty sturdy components so I don't believe this has happened in storage or transit. Buyers beware!
