### 5/5 — Works well

*2024-06-12*

App does exactly what I expect it to do and is handy

### 1/5 — False advertising

*2022-09-26*

If needed, the app might be good. But the free download is just a waste of time if you don’t plan to pay to use the app monthly or yearly and the rates are not cheap.

### 5/5 — Accurate prices and large database

*2022-05-07*

This app is a popular app used by many converter dealers and has a huge list of Catalytic converters of top auto car manufacturers with super accurate prices. It came highly recommended by a business associate who also uses it. Unlike some of the other apps that are ridiculously priced, this app is reasonably prices and is totally worth the cost. It has been a huge help to me in my business of trading in converters. A big thank you to the developer!

### 1/5 — Stuff they don’t tell you

*2021-11-26*

Might be an alright app but they fail to tell you that you need to pay a hefty price before you can see pricing. Reputable companies would tell you that BEFORE you sign up.

### 5/5 — Amazing app for Catalytic Converter

*2021-09-07*

I have used this app to find prices for my Catalytic converter and it is very accurate. The app also has a lot of information like car make, images and has a large number of Catalytic converters. Best of all the developer has priced it well. I don’t have to pay the ridiculously high prices that other apps are charging. A must have if you trade in Catalytic converters.
