Great fun to put together, gotta be delicate or you'll break it. Need better lubricant for sliding the wood together.

I actually was eyeing the marble run first, but since I haven’t done any from this brand before, I figure I should start with something simpler.This is a very well thought out 3D puzzle, and the finished product looks exquisite. My problem is really with how hard it is to get some of the pieces in place. I mean I have very little grip strength, so the later steps where you have to wiggle and force a piece in place was very difficult. And the wooden pieces aren’t strong enough to withstand some hammering. Luckily, with the help of my 8 yr old toy hammer and my trusty tweezer, I manage to softly bang some of the edge in without damaging the wood too much.The instruction isn’t exactly crystal clear, took me a page or two in before realizing pieces with + sign next to them are extra pieces. And I was kind of hoping my lego/puzzle savvy 8 yr old could have enjoyed this project with me. Nope, he might be able to follow the instructions, but to build this thing, a child needs to be pretty advanced in manual dexterity.Anyway, it took me about 2-3 hours, mostly trying to figure out how to bang/wiggle things into place. There were a lot of doubts as to if the finished project would actually work or not.It did, and frustration aside, I am impressed with the design. Definitely worth it if you enjoy building this kind of puzzle.Now I am thinking about getting multiple others to build and gift, since you can hide trinket in there.

This was my third ROKR model and i was impressed with this one. Directions are easy to follow. finished product looks professional. Really works, and is accurate. My only complaint is that the winding only lasts a few hours, but that is what they advertised, I wish there was a kit that could make this self winding. I would recommend for fun or as a gift.

I upped my rating to 5 stars. I finished the calendar and feel ridiculously proud of myself. I really didn't think I would be able to figure out the directions since I've never constructed anything more complicated than a Mr Potato Head. But the directions are actually quite good, the parts fit together precisely, and I got advice from the manufacturers via their facebook page when I had a question. The company rep was exceptionally nice and helpful. It takes patience and care, but you don't need to be Einstein to do this.old review-I just received this model and am already confused by the instructions for step 1. The instructions are not clear and detailed enough for a novice. There should be instructional videos for ALL of these puzzles.I haven't begun this yet, but I can see that building this will involve a lot of guess work for me as to what the illustrations in the manual mean. I will be very disappointed if I find that I have screwed up somewhere along the line and am left with a little pile of kindling.I'll try to update this review when I'm done trying to put this thing together.

I did like working on it and it was not too difficult. but I am still trying to understand the working of the pendulum. I mad 2 more ROKR products before, ' Locomotive and Marble squad, and I have ordered a new puzzle which have not arrived yet.
