Wooden Roller Coaster Marble Run Puzzle - ROKR 3D Mechanical Model For Self-Crafting, Decoration, And Educational Gifting Review

My review is for the "marble squad” version of the kit.This is a complex kit that works surprisingly well for something with 8 metal pieces and hundred of plywood bits.The design is very thoughtful and a lot of work went in to designing something that’s difficult build wrong:* every piece has its pet number etched *on* the part so you can identify it even if you pop it out too early* all identical pieces have the same part number making it easy to keep parts sorted* lots of pieces either can’t…

This is the 3rd of these ROKR "coasters" I've purchased, and the other 2 models operate very well. This one was much more difficult to assemble and is apparently VERY sensitive if you don't get the pieces assembled with laser-like precision. Marbles continually fall out of the coaster and get hung up in multiple places. Suggest you purchase different model(s).

This puzzle was the most challenging and rewarding that I have ever done. It requires lots of light to connect the pieces and lots of patience. My wife helped with the instructions and confirming each step's installation. That was a big, big help. The assembly instructions were very good (no errors) but there were a few steps that I would have changed the order on. We ordered another ROKR puzzle! [Note: the puzzle was not "easy to assemble" but I gave it 5 stars anyway because assembly wasn't…

bought for 10 year old. He loved putting it together and was about 6 -7 hours of challenge and fun. Running the marbles once assembled is limited however. The light wood pieces break and lose their connections fairly quickly. We started using glue to keep some pieces together, but just not really built to last. Maybe next gen. will be better.Looks great on a shelf.

This is my twelfth wooden puzzle project and I just ordered my thirteenth. From different company's. These are excellent winter projects. I particularly like these marble mazes. This is my third of these and I have motorized them. They are entertaining to watch. These puzzles can be quite challenging at times. Just be patient and take your time there is much enjoyment to be had. I have gotten these for my last three birthdays and I look forward to them. I am sixty-seven years old and eight…

took me about 4 hours to put everything together. instructions were good, didn't have any issue with pieces not aligning as i read on some comments. i am very satisfied.

My husband is a jigsaw puzzle maniac so I got him this for his birthday. He has already put together two similar puzzles - the locomotion and the clock. I love this one because it is fun to play with!

I've done a few models from different companies, this one is superior and worth the build.Only warning. when hanging pieces V, W, and X, make sure you hang them in the correct direction. I had one reversed and had to take the model apart and rebuild it. The little tab is off center, on one side of the piece. This dictates the direction it flaps. I can't remember which side it should be on, sorry, but look very closely at the diagram and try to figure it out.

We have 3 of the 4 of these now with the forth on order. The Marble Parkour was our first and it was the easiest to assemble and it worked fine right away. It is great how it chooses between the two paths. The lift coaster was the second one. It is much more difficult to assemble and the lift would not lift high enough to drop off the marble. I had to do three modifications to get it to work. It still is not perfect but it does work now and is fun. The third was the Marble Squad. It went…

We bought this for my 11y daughter who asked for it for the holidays. It was really fun for her and I to put together and she loves it. Some of the pieces are hard to get out so make sure you use the tools it comes with.

I seldom write reviews of products but this kit is simply amazing. It is so beautifully designed, laid out and laser cut that I wanted to share how delighted I am. There are 239 pieces in the kit. No glue or other fasteners are used because each piece is a press fit into other pieces. To make this work, very close tolerances must be held in the cutting process. The laser cuts are perfect. I'm incredibly impressed with the thought that went into this design. Like Salieri, I'm just smart enough…

Puzzle didn't have all the pieces. Bought this for an anniversary present. Started assembling the set with my hubby yesterday only to find that the spacers were missing. I emailed the seller asking for the missing spacers, was told that I lost them and to replace them with paper. I didn't lose the spacers, they were never there, both of us checked several times. I don't care if I can make my own spacers out of paper, this puzzle was expensive, I want all the parts I paid for. Tried to contact…

This was a great gift to get the kid off the screen. We spend hours assembling this together. After completing it, we left it on the desk and he can crank it whenever he is bored.

Another challenging and satisfying wooden mechanical kit from Rokr. I found this to be more involved and difficult than the Rokr Pendulum Clock I built previously. In addition to a base, support structures and multiple marble ramps, the marble run is made of up three complex subassemblies: a hand cranked gear mechanism, an escalator mechanism and a stacked ramp mechanism with swing gates. Not only are there a lot of small parts in each subassembly, but the final building stage of each involves…

It arrived without one of the parts sheets and the balls. I don't understand how that can happen when the sheets were all shrink wrapped together. Not happy!

After several days of assembly, i'm ready to pitch the thing into the trash. Many of the parts break simply by removing them from the 'punch board.' Then you need to glue them back together. Instructions consist of a booklet of pictograms that, quite often, are meaningless. But the worst. Some of things you need to assemble require an act of God. I've got to wonder what the designer was taking at the time.

The main wheel where the balls are supposed to feed into the product isn’t cut right to allow the balls to work. It was a lot of fun putting together but it can’t work.

The use of an exacto knife, magnification and misc small tool like a hemostat, make the assembly easier. This is good Covid stay at home activity.

I gave this to my brother-in law for Xmas. He started on it the day after he got home & finished it by the next day. He said he really enjoyed putting it together. Playing with it was a bonus.

This puzzle was amazing for me. It kept me occupied for quite a long time. The instructions were about 99% clear. There was only 1 thing I had to figure out on my own, but made sense when I did. This was a lot of fun to build. I will definitely be buying the others!I mentioned to my wife how sturdy the wood is, considering how thin it is. It's definitely designed to stay together! I can tell a lot of thought went into the manufacturing of the pieces
