## Customer Reviews

### ⭐⭐⭐⭐ Used for years
*by E***D on January 21, 2024*

I have used Guson Colortune for years. I use this for LBC MGB 4 clinder cars. I think the results are good, but can be subjective when comparing colors.

### ⭐ I won't buy another one.
*by M***E on October 1, 2021*

You use it to help gauge air fuel mixture but the one I received misfires about half the time, causing the cylinder to load with fuel. Which makes it impossible to use for the intended purpose.
