Rubbish.
I buy this thing it’s going to be amazing because THATS WHAT THE FLYERS SAY. But what they forgot to mention, is that THE CAMERA IS INVERTED SO YOU CANT SCAN IT. Come on. If you want to make a good app just check if every thing works! It’s easy. However, where the parts list and everything else is pretty cool, but unless you zoom in (which this app DOESN'T let you do) you can’t read the manual because the writings tiny. The actual model though is absolutely amazing. Took me a bit of time to make it, but the finished product is really cool; plus, it actually works, unlike some other things I’ve built. Final score: model is ⭐️⭐️⭐️⭐️⭐️ and app ⭐️. You need to work on your tech skills.
