## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A good value product
  

*by D***) on Reviewed in the United Kingdom on 28 February 2023*

I bought this for a project at good value, simple to assemble but would have been better if the assembly instructions came with it rather than having to search online for them...

### ⭐⭐ 2.0 out of 5 stars







  
  
    No instructions
  

*by A***H on Reviewed in the United Kingdom on 9 December 2023*

No instructions and ones on website don't tie up with the actual board

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Okay
  

*by A***A on Reviewed in the United Kingdom on 24 January 2020*

Just about okay.
