OUR NEWEST VIDEO just hit 250+ comments, so Tier 2 is officially unlocked. 👀
That means the giveaway just got better. The current prize is now a Kingbolen S608, and if you guys keep pushing the comments up, the prize keeps getting better.
The video is actually about something I think is pretty interesting: does having a good scan tool actually make you a better technician?
I get asked about scan tools all the time, so we put the Launch X431 Pro 3S+ Elite through its paces and talked about what these tools actually do for you as a tech.
And somewhere in that video is the question you need to answer to enter the giveaway.
So watch the video, find the question, and give me your best answer in the comments.
I’m reading them myself and picking the answer I think is the best. Make me think, make me laugh, or give me a perspective I haven’t considered.
And share the video. Get your buddy to watch it and answer too. The more people who participate, the bigger this thing gets.
Right now:
250+ comments = Kingbolen S608
500+ = Launch Creader V3.0 Elite

And we’re going to keep going from there. The giveaway can reach up to $600 value.
I’m not putting the question here because that defeats the whole point. 😂
Watch the video, figure it out, and give me your best answer.
