## Customer Reviews

### ⭐⭐⭐⭐⭐ outstanding product with great results
*by T***D on 16 August 2018*

bench test shows this product really does work but can be purchased for a third of the price elsewhere.

### ⭐⭐⭐⭐⭐ Good product, cheaper else where online
*by M***E on 18 May 2018*

Superb product, really does work on your engine, but why pay 60 to 70 GBP, when its a third of that price online and cheaper, ie: £27.99
