Review on ROKR Assembly Mechanical Christmas Valentines: Perfect DIY Gift to Celebrate the Festive Season! by Nick Mcvey

Great puzzle car! This was a surprise for my husband because he was bored all the time at home. It took a week to convince him to put it together, but once he started he didn't stop. It took him several hours, maybe four or five at a leisurely pace. It wasn't very difficult, you just have to be careful. The instructions were very clear, there was even a video to watch but he didn't need them. A few really tiny pieces broke trying to get them out of the board, but there were some left as well. I had to glue a few pieces to keep them in place. Worked very well once assembled, small adjustments to keep balls from getting stuck or falling out but no major issues. I will buy more!
