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

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

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.

Found some of the parts very fragile and breaking when trying to lock in place. Not as robust as the Clock type products

Relaxing but sometimes frustrating! It's sturdy enough but you have to be careful when assembly as some pieces are easily breakable. I had to use a little bit of glue here and there just for my own sake. Definitely not a puzzle for kids. Took me 8 hours to assemble

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.

Cool 3D puzzle. Fun and challenging to assemble - good instructions but does require a little skill/patience. Neat to play with after finishing - doesn't just sit there and collect dust.

This thing was so fun to put together. I have big meaty sausage fingers so I found it a bit difficult in some tight spots but I managed. I broke one small piece that I had to glue back on and I had to sand down a couple of places to get the marbles to move a bit more smoothly. Other than that it functions great. Its such a cool thing to have and everyone that comes over plays with it. This was well worth the price.

The kit is a work of art! Very impressive manufacturing... That said, this build will absolutely test your patience and core finger strength. Parts are very fragile and difficult to assemble. You need to apply just the right amount of pressure in just the right place -popping out the pieces and putting them together takes a lot of focus. Sometimes felt like using my whole body stength to fit these tiny wood pieces together without breaking them. Precision pressure and patience is required. Instructions have some errors. Expect frustrations. Work carefully. It's a neat build
