Well designed!
At first, I was afraid that this toy would break easily and it wouldn’t be worth it. However, this building toy is well designed and great for kids who want to build things. Keep the pieces together so they don’t get lost! This is a great buy and I really recommend it!

Great fun with assistance
I bought this for my 7 year-old grandson. His 12 year-old sister was very excited to see it because she always chose this as a free time activity when she was in the second grade. The directions were a bit too complicated for my grandson to follow, but he helped her complete the first vehicle. It was great for the two of them to work on together. I hope they do more projects as well.The pieces are pretty sturdy. They wanted to give it a 4 1/2 star rating. My grandson says, “it’s great”.

Great Buy
Bought for my four year old and he absolutely loves this. Really like that it comes with two screw drivers with toddler handles and two wrenches. Makes sharing with brother and help from parents a lot easier. I can see him using this well into elementary school so we will definitely get our monies work.

Good but…some issues
This is easy for little hands. This works like real tools, as you need the wrench to hold in order to tighten certain things, however on the first build the wrench broke, and not repairable as its plastic, of course. It was given as a gift and we have been building things since then. Easy to follow directions, however some of the items the directions have to be altered as they must not have thought about the end user making the item and screw placement etc. We are still able to build but out of the 4 items we built 2 have had to be altered in order to fit with screw placement or materials being able to mesh flat.

Great toy if you like building together.
Great building toy. Pictures and instructions are easy to follow.I immediately put the pieces into a larger plastic bin to make sorting them easier.I bought two of these for me and my grandson to have a next level building activity.I thought that we would be building the same car or airplane independently, but some of the activities were too difficult for him. So we settled into him finding all the pieces for each step, handing them to me, and then he used the driver tool. I am glad I have two sets so each one of us has a car or plane to drive around.All in all, I have enjoyed this building toy. I think it is well made and well thought out.

Very nice toy
Very nice building blocks set, if you go with your own custom designs – you can buld more than one toy. Quality is good, ideas book is good both in terms of quality of print and ideas. You can find/buy different compatible sets with different pieces (some even include toy people) and make it even more enjoyable (but be ware that there are offerings with different pictures but with same building blocks/pieces so look carefully). For the price (about $21 with coupon discount I’ve got) I think it is a good deal. On the pictures you can see a few of toys we’ve built, not from the book.

Di seguito proverò a riportarti la mia esperienza veritiera e disinteressata con l’articolo in questione che arriva nella sua confezione brandizzata……sperando, così, di riuscire a darti la possibilità di prendere una decisione più oculata in merito ad un eventuale acquisto; fermo restando che, pur provando ad essere il più possibile oggettivo, sarà sempre un mio parere soggettivo.All’interno troviamo 110 pezzi di costruzioni ed il manuale d’istruzioni.Realizzate in plastica ABS colorata ed atossica, queste costruzioni sono molto diverse rispetto le classiche “LEGO”, ma ugualmente facili da assemblare e da giocare.Robuste, si incastrano facilmente e permettono di realizzare 18 modelli preconfigurati, presenti sul manuale d’istruzioni.Ottima, inoltre, la scelta d’inserirci all’interno del set 6 ruote, così da poter realizzare veicoli articolati più complessi.In conclusione posso scrivere che queste costruzioni mi sono piaciute in quanto oltre a sviluppare la coordinazione oculo-manuale, la capacità di risolvere i problemi e l’abilità cognitiva durante la costruzione dei modelli, vanno a stimolare la fantasia e la creatività dei nostri bambini una volta che iniziano a giocare.Il costo è un elemento importante da tenere in considerazione, ma esulerà dal voto finale in quanto voglio condividerti solamente la mia esperienza con quest’articolo, poi starà a te valutarlo globalmente.Quindi, per tutto ciò scritto (basandomi sull’articolo arrivato), la mia valutazione è 5 stelle su 5.📌 Ps: In caso di problematiche o novità rilevanti effettuerò un aggiornamento.Grazie per aver letto le mie parole e mi auguro che questa recensione ti sia utile……alla prossima!
