ROBOTIME 3D Puzzles Marble Run - LGA01 Marble Night City Wooden Model to Build - Model Building Kits for Adults

The packaging was very well put together and they supplied plenty of extra parts to help put the model together. The instructions were easy to follow and even my seven-year-old was able to help create the track system. He received this from his grandparents as a Christmas gift and while it was a little too advanced for him to put together, he did enjoy helping out with the easy pieces. Once complete he was raving at how much fun it was to watch the balls in action. He hasn't stopped talking about it to his friends.

The kids loved if.I almost went crazy trying to assemble it - but it is a puzzle after all.I’m shocked how well it worked when you got it all put together.Fun family activity- especially to get the family away from screens.Keep in mind that some of the pieces are very small, thin, and fragile- so may want to supervise younger kids under the advised age.

Assembly is reasonably challenging. Fully and properly assembled it works wonderfully.Be certain to have some gel type super glue on hand. You WILL need it! Unless you have small fingers you will need a pair of long, delicate needle-nosed pliers.I'm very comfortable with pictorial instructions and these were fair. The background illustrations were too faint in my opinion however and some steps were out of order with testing omitted.The long twisting return ramp path works perfectly with a single ball but will shift due to the weight of multiple balls in the event of a clog.Some things I learned:1) The ramp/rail assemblies at the beginning should be glued together with gel super glue. Glue the brackets to the ramps from beneath. The "ribcage" section does not need to be glued.2) After step 9 skip ahead to page 22 (step 23) and glue on the rails. Glue everything except parts A29 and do no press parts A29 into the ramp--only the rails.3) In step 13 be certain that the clear plastic "keys" are hanging down to the right as viewed from the "ROKR" side of the assembly. When the assembly is complete test it by putting a ball in each hole with the "key" dangling below. Use a ball point or similar to push the key from the short end opening and the balls should fall.4) Secure the ends of each wheel assembly with some glue.4) Before you mount anything on the base skip ahead to the final step and add the feet and identification plate. If you don't add the feet the base won't be level and testing is nearly impossible.5) Periodically test the ramp during with a ball during step 23. The sections must be FULLY pressed down onto their mounting tabs! This is not particularly and they don't always like to stay that way. Once you've installed the "ribcage" section, test thoroughly. When you're pleased put a dot of glue on the top of each mounting tab where it comes through the ramp. Set aside for a while and take a breather.

This item very cool. I bought it to my husband, a Christmas gift. He was so excited and opened after receiving it. It’s good quality, very well packed, cool looking, strong and working well. The instructions was very clear and detailed, easy to follow. There were many extra items if you mistakenly broke some tiny parts. Love this one. Worth the money! Thanks to the seller.

Honestly, I’m a bit disappointed in the product. It’s almost a really good marble run. The run design is great. The quality/ ease of assembly/ fitment/ sturdiness of the pieces resulted in many broken parts, tons of frustration, and in the end something that resembles the finished product but is not usable the way it is advertised. Some of the features simply don’t work and some require a bit of coaxing to keep it moving. It may be that it requires a lot of patience and a very gentle approach to assemble. But I think it’s nearly impossible to assemble flawlessly without breaking some pieces. The fitment of pieces is not the best design. Have lots of glue and patience on hand. Not recommended for younger kids. My advanced 10 year old struggled with it as did his dad!Also missing one screw for the handle and I ended up creating a work-around/ using my own hardware.

Most pics aren’t always accurate…one mistake changes all functions

I liked the concept. The pieces dont stick together. Instruction are a joke. They even say if the wood breaks (which they are expectinf it to break) glue it togetherAnd when you manage put them together. You move on to adding more stuff to it. They come un done so you have to go back. 0/10

Excellent
