We ordered the marble run for our son's upcoming birthday but realised straight away that he would want several sets to make more complicated runs. When we contacted Kingdom Playroom they set up a special code, specifically for us, so we could take advantage of the discount available on a multi-unit purchase. Incredibly fast, friendly and helpful support with a great product too! Highly recommend!

This is a great addition to a duplo set.
I purchased 2 sets a I didn't think one would be enough for more crazy idea marble run formats.
Pros.
# fits well with Duplo blocks
# there are enough turns with 1 set, but more options with additional sets.
# The balls are a good size.
# Easy enough for young explorers to use.

Cons.
# Wash before use. They had a powder film on them.
# As mentioned in the description, the colour varies. Which isn't bad until the instructions.
# The instructions are horrid. The diagram is super small and not viewed from angles that are worth it. Plus colour variants. This isn't important with free play, but frustrating if your explorer likes instructions.

Overall, one of the better basic marble run sets that can be linked with blocks.

So much fun my daughter loves playing with theses blocks. They are very similar to the Duplo blocks the only down side is the packaging, but excellent customers services makes up for it .

Received it in just under a month during the lockdown. The quality is good, everything is sealed in a plastic bag. I ordered two sets and they came with instructions. Very happy with my purchase!

My four year old son is thrilled with this. Arrived in good condition, well packaged.
