This was an above average marble run kit. It's my 4th one and this one has a few features I really appreciate. I liked that Rokr didn't stick with plain unfinished plywood. The inclusion of some plexiglass and colored wood made for a more visually interesting build and using metal axles made this one of my smoothest running kits. This certainly shouldn't be your first build, but if you've made a few you'll have more than a few challenges, but not many frustrations. If I had to pick nits, I'd say I'm not crazy with the way the ramps fasten to their mount. They're not terribly secure and can come out of alignment if the base flexes a little. In addition, towards the end the illustrations get a little lazy and they clearly want you to refer to the video (which seems like cheating to me)
