While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Rislone 4720 Cat Complete Emission Cleaner

I bought their 4720 Cat Complete Emission Cleaner that is supposed to have a full money back guarantee. Their product didn't work, I applied for a refund. I filled out their forms, sent them everything they asked for (to the letter) back on 7-7-26.
Today on 7-27-26 I received a call to tell me I was denied a refund. No honest reason given. They simply do not stand behind their guarantee, shame on them.

Buy it if you want, don't expect it to work. You'll not only be disappointed in the product but the company as well.
Just for some background, I'm a retired mechanic with over over 40 years experience. Take it for what it's worth, but I will never buy another one of their products again.
