I was excited to see a clean setup only to realize after installing the pivot balls that it all wouldn't work. Fitment of the pivot balls seemed inconsistent as well where some were tight and others were loose. I've tried contacting the company multiple times only to be left waiting for another follow up.
I was excited about this purchase because PowerHobby had the best price. Unfortunately, the slot car arrived badly damaged - both front wheels had come loose in the box, and appear to have rattled around damaging the fine details of the front suspension. PowerHobby's return policy made return of the car and purchase refund very straightforward.
5/5 stars because the adapters are very convenient for all different types of cars
