Marbelocity 4-Bar Link

It's a great, new addition to the other two min-marble run sets and integrates well with them. The simplicity of design means a solid product, and I like the tactile quality of the games as a better alternative to digital apps designed to simulate gearing and mechanics. Great way to introduce kids to design, process, construction and mechanics.

This was a fun kit to build and the first one where one of my children helped for the entire build of one hour. The instructions are well written and the kit was easy to assemble. Our only issue is that the balls tend to exit a bit too quick and jump off the landing platform. This is solved by adding a small strip of wood or putting it together with our other members of the series.

As a Speech Language Pathologist, I use these with children and adults! My preschool and kindergarten students love to build with these, and I often use them as reinforcers during therapy. I also work with adults in a skilled nursing rehab setting and they are great for motor skills, sequencing, and problem solving! They are sturdy and easy to grasp for all ages. The set includes plenty of pegs!

My daughter enjoyed putting this together. Needed a bit of adult help to be sure exactly what to do, but overall directions were clear and well written. Liked the extra educational cartoon book to help bring the mechanical engineering piece to everyday objects. I like how you can integrate this with other kits to add to the learning.

My kids love this set! My son (5) likes to stack all the pegs and hold them out horizontally. My daughter likes to put the pegs in the crepe board. This set is great for fine motor skills, sorting, and patterns. I love that the pegs are the same ones in the little builders set so when the kids grow out of this set it is still usable!

Built this with my son and he loves to play with it! He learned a good amount about physics when we built it and its good at teaching S.T.E.M concepts. It is modular and can be integrated with other Marbleocity products. If you do buy it I would be the optional motor as well since hand cranking it isn't the best.

When I got this marble run everything came in a small card board box. Inside, everything was sorted into bags or part of flat pieces of wood, ready to be punched out. The instructions were easy to read and with their help I was able to quickly construct the marble run without a problem. When it finished drying, the marble run was very sturdy and the marbles were just the right weight: not too light yet not so heavy that they jumped the tracks.

The small Triple play builds are quick and solid but are a fraction of the size of the full-size Marbleocity sets, which are awesome week-long builds (multiple steps and dry time) that are well suited for parent/child bonding. Alternatively, the Triple play builds in under an hour. Definitely recommend the full-size options as first choice.

We all had fun assembling the unit. It took us about an hour to build. Using toothpicks to put on the glue is a great tip. Having small fingers also helps. The text in the instructions is small with low contrast, but that meant I had the kids read the instructions out loud, which was an extra learning opportunity.

It was a fun project to work on together with my children. We had to modify some parts of the track to ensure the steel ball did not jump the track. Overall it is a good product to enjoy building and playing.
