To be honest, Hack Pack seems to just coming out of its beta phase (the website says the subscription is currently for early adopters), but things are definitely constantly being worked on to make it better. Since replacement parts if it doesn't work are completely free, it's basically guaranteed to work eventually, in the rare case that it doesn't work for you right away. It's been fun talking with people on the Discord and helping people find what is causing their issues =P

To the other low reviews about loose connections, since they remodeled the breadboard version this should be muuuch less frequent of an issue - if it's an issue for you and you request a replacement, they'll send the new version. To the one review about the domino bot not turning on, this happens when you accidentally connect some of the red and black wires backwards (which lets the power flow straight back into the battery without powering the arduino, this is called short-circuiting).

Thanks to Mark, I started diving into the world of coding micro controllers. I love this! I completed this project and I am playing with the code now! Thanks for your thoughtfulness to design this! Looking forward to more projects soon!

I’ve always wanted to try hacking and coding, this made it really easy! The videos made the build easier than I thought, and I really recommend this. Small thing though, the darts are hard to put on, but it’s worth it! Can’t wait for the next box! Thank you Mark Rober! ⭐️⭐️⭐️⭐️⭐️
