Typical example of another Chinese app in the US market with fake prices and no customer service. **Developer response:** Dear User, thank you for your comments. We would like to support you with this issue and so we’d appreciate it if you could clarify the details of your problem at support@autocatalystmarket.com. ### 1/5 — another garbage *2021-06-17* trash…is probably the softest way I can describe it after downloading. To see the price I first have to give them all access to your info and email …and right next page is a plan offer. You can’t see Sh🤬t before you pay. not even a single try !!!! You don’t even deserve a single star for this app!!! Eco Cat is way better.!!! **Developer response:** Sorry to hear you are unsatisfied with the app. If you have any suggestions, please contact us at support@autocatalystmarket.com We hope you can enjoy our app again in the future Best regards, AutoCatalyst Market Team.. ### 1/5 — ДОРОГО *2021-03-09* Сделали бы бесплатно **Developer response:** Чтобы сделать хороший и качественный сервис нужны финансовые ресурсы.

Now the application is working stably and the service is dynamically developing. Try it now and rate our effectiveness! ### 4/5 — Decent *2022-07-16* I like the app because of huge database they have but prices feel off. Most of the time too low and in rare cases way too high and i do compare them with actual value. Photos also could be added consistently. Overall good , would give 5 stars if fore mentioned issues are solved. **Developer response:** Hello. Thank you for your review. The cost of the catalyst is based on the utilization price: The number of pt/pd/rh precious metals is multiplied by the cost of metals (taken from the Kitco exchange) and by the monolith weight. Then from the price are deducted: manufacturing recycling costs 1% moisture losses during metal refining logistics costs Buyers in each country/region announce their purchase price based on our catalog prices with a deduction of about 5%-30%, depending on the market situation and on the batch size.
