ROKR 3D Wooden Puzzles for Adults Marble Run Model Building Kit(LGA01 Marble Night City)

11/12/22I’ve had this sitting on my kitchen counter for about 10 months now. It’s been a conversation piece and it’s been enjoyed all that time so it’s was definitely worth the hard work and time it took to build it. My wife even enjoys it being there. Kids seem to enjoy it the most and marvel at how it works.However, one energetic kid was a bit too forceful with it and broke off the handle. For longevity, you need to tell everyone to be easy on it and not force things since gear meshing etc can momentarily bind.FYI The handle attachment is a weak link which breaks before other more complicated pieces break. It is easily fixed by gluing a patch piece of plywood over the broken area.Original reviewI like the way this kit turned out a lot. The pieces are of high quality and fit together nicely. It’s a lot above average in difficulty and you’ll need persistence to put it together. Also there are a few areas that need tuning that I describe in my video. But once it’s tuned it works great. To summarize, you’ll need to a) add a guard rail to stop the ball bearings from occasionally exiting the spiral. You can use the left over original plywood cut out. Just find a 5” diameter guide pieces (I used 8mm film can) and use it to cut the outside diameter of the spiral. b) put a plywood wedge with 45 angle under one drop hole (finger points to location in photo) to kick the bearings forward and keep it moving c) add the correct number of spacer rings so the bearing drop freely between the plastic pieces and d) adjust the play in the flip-flop so it alternates properly. Mine works very well and people really like it as do I.

While this is definitely not for kids, I really enjoyed putting it together. The pieces are very accurately cut and well-marked. You have to be careful not to break them, some a pretty fragile. Once you get acquainted with how things go together it isn't a problem. I broke a couple of pieces, but they were easily repaired with some wood glue. The instructions are all pictures and some were a little small, but I took a pic with my phone and zoomed in to figure those out. There are also some videos that help (QR codes in the manual direct you to the videos.) There were a couple of times that i tried to make something work before completing the assembly and was worried that things didn't align properly, but later steps in the assembly fixed every issue. If you are impatient, or have trouble following instructions closely, this isn't for you, but I loved it. I ordered my second one just a few days after completing the first one. Highly recommended.

Lists as HARD. I didn't find it hard to do but the assembly took more time because of the time it took to glue pieces that broke. This is a very delicate project. Pieces are narrow and break easily even when you are being delicate and using tools they give you. I haven't quite finished it yet so I don't know how durable it will be. Still I like building and fixing; I just wanted to give a heads-up. Other than that, instructions are good and all parts (with some extras included) were enclosed.

This is a 5 star product for me. I did break two pieces, some of the pieces were very difficult to push together, and it doesn’t work perfectly every time. I did also use a little super glue in a few pieces. However, the design of sending a few sheets of balsa wood, to make something like this had my wife and I blown away. It’s super impressive… I thought my 5 year old and I could do this together, not for kids lolSome comments reference a few of the issues I mentioned as reasons for knocking off stars, it’s a delicate, very elaborate, balsa wood marble theme ride… it’s not made of plastic and it’s not supposed to be a quick throw together project. The fun is in the assembly. So carve out a few nights, or weeks and enjoy this marvel!Thanks for a challenging and fun build. Highly recommend.

I’m not a puzzle guy, but my wife’s family loves flat puzzles.i bought them all ROKR puzzles suited to their likes last Christmas. I don’t believe they ever ended up building them, but I figured I would buy one for myself this year because I was intrigued. I had so much fun building this thing. I was so locked in. Once I finished it, it didn’t work the way it was supposed to, but that was my fault on a few different steps. I’m going to buy these these puzzles one after another. I have found a new hobby thanks to this puzzle. 100 percent recommend purchasing this. The instructions and build kit are perfect. Can’t express enough how much fun it was to find a new hobby like this. Thank you ROKR. Also if you want to send me any for free that would be awesome haha regardless I’m going to continue to keep buying them!

Rokr really dropped the "ball" on this one! Do yourself a favor and click on the reviews...go to the 1 star reviews....read them....and believe them!!! I've assembled probably a dozen Rokr sets and this was just awful! The build was frustrating. Parts broke very easily and it's almost like they added steps after the fact and made it so difficult to assemble. Things didn't line up properly or snap together well. If i was able to finish, i can just imagine how badly the marbles would get stuck. Too bad, cause i enjoyed their stuff. But a big fat NOOOOOO on this one. Return!

Took my brother about a week to make. He normally breezes through the Lego sets and this was a great match for him

I had some pretty decent fun building this track up until about 75% through where I broke a piece that was irreplaceable. Following that, I started noticing assembly issues where the pieces wouldn’t fit together tightly enough and would keep the track from functioning, then pieces that were too wide and thus couldn’t fit into their intended spot. My point is, the puzzle looks cool and has many unique and interesting concepts that I wouldn’t usually see, however function is definitely not something you should be banking on, as most of the track is completely inaccessible without personally placing the marble on it.

Nice to do something non-digital. And looks good on display

I got this for my daughter after she saw a friend build one, and she was really excited to try it. It’s definitely more complicated than LEGO (and she loves LEGO), so be prepared for a bit of a challenge.The detail and design are really impressive, and it’s very satisfying once you start seeing it come together. That said, it does take patience and careful assembly—this isn’t something you rush through.In the end, it’s a great hands-on project and a fun way to build something unique. If you enjoy crafts and don’t mind a bit of a challenge, it’s absolutely worth it.

This was a Christmas present as a surprise for my husband. Unfortunately it was not a surprise as it was just the product box with the label on it. Being put in a padded bad would have been great as the box was damaged. The product itself was luckily not damaged and was great.

Extremely frustrating. The parts don’t align perfectly, don’t fit tightly and keep popping up/out during the final assembly..especially the rails, so the marbles don’t run smoothly. Don’t recommend this product.

Very well made. Takes hours to do and lots of fun.
