I Support the Concept

I have done some research into this project and felt the need to invest in it. It is proving to be worth the cost. Only problem is I already pre-ordered the videos online on my account, but the app says I still need to pay $20

Noob to somewhat competent

This course took me from complete car noob to being able to feel confident in making repairs and not getting ripped off by a mechanic. The videos are super high quality with a good dose of humor. Things are explained incredibly well in both the videos and written content. I paid early on for access and have had no issues with accessing the videos. Keep up the great work!

P.S. I have yet to come across a “tear down” but I have yet to read all the articles so I’m sure they are in there somewhere.

P.P.S. To anyone who says the AR is not great; It has frikken AR! That is more premium content added on top of the already amazing amount available. To me it shows the dedication to using technology to teach these concepts.

Videos cause crash

I want to love this app, but the video courses cause the app to crash as soon as the list of videos opens. Also haven’t had any luck with the AR feature; maybe I haven’t found a flat enough surface. The articles are full of great information and images, hence the two stars. For $20, though, I would hope everything would work flawlessly, especially something as basic as loading videos.
