Pack curieux

I bought these both for my nephews, who live in a different country.
Firstly - there are no big metal parts or batteries and these were "ok" by TSA, in both check-in and baggage, in case someone needs this info.
Secondly - the quality. These are made of plastic. At first glance, since the parts are very light, it seems cheap, but I assure you, it's not. My nephews dropped the parts multiple times, fitting wrong parts forcibly, and pulling the strings to their limits. Even the smallest, thinnest latches are very durable. I hope that these will be passed down to the younger siblings, atleast, if not next generation.
Thirdly, and most importantly - the experience - it was the best. Its not just a great learning game, but when the kids were not doing the puzzles, they started making random circuitry using imaginative arrangement of the parts. I think that is the best part of any game, which lets kids use their imagination, as much as they desire.

There are other great things which have already been said in other reviews, so I'll keep it short.
And THANK YOU!!!! to the Upper Story Team, please keep doing what you're doing.
I'll be back for more.

Wow enfin des jeux de qualité , bien pensés et bien fabriqués. Mes enfants et même nous les parents avons du plaisir à les découvrir! Je les ai recommandé à plusieurs personnes !

Both sets are wonderful. The comics and challenges are beautifully illustrated and well thought out. I bought them for my kids who are 5, 6, and 8, and they all enjoy them immensely in different ways. It's a fun activity to do as a family as well. It's amazing how well the pieces for together and how well it works as a concept. The customer service has been great as well. Will likely be ordering the expansions and sets for gifts!

My Boys and their father have been crazy about these games and the stories that go with them since Christmas! I’ll have to start at the beginning but they are the perfect blend of trial and error and they make learning fun!

Excellent product worth tge price tag

Je crois que c'est des bons jeux pour développer la réflexion chez l'enfant.

Ask in November and I will give you the feedback that you are asking for.

High quality product. I’d recommend this for any age. Super impressed.

Very well made and excellent learning opportunity.

I would give it a zero stars for ordering. A five stars for shipping and a five plus for the items themselves. Superb for my granddaughter who is ten years old. This will keep her occupied for the whole summer. She loves lego puzzles and is a straight“A”student. She loves the challenge and fun. Excellent product .
