This is an awesome product for building knowledge base of your kid and engaging them in some productive work. This product contains user manual which helps to build the product very well. Mechanism used for this product is very creative and innovative.Highly recommended to buy this product.

wonderful!!! a must have children's DIY project for a fun and highly engaging way of learning

Product is good and will sure engage the children and make them learn the concept better but the pieces are dangling after assembling that is it's slightly on the smaller size that it suppose to be so it makes the output difficult for children as they are loosing the interest continuously reassembling it.

I have bought similar products before and therefor when I was pressed with gifting something for a 9 year old on his birthday, I straightaway ordered this one. Later I learnt that not only the kid but his parents too enjoyed assembling the lock. So, I am rating it as 5 stars.

Nice product, will improve imagination of kids. Kids will learn and play with it. Assembly description is very good and easy to understand

This is a well made toy. It engages the children creatively and helps them to understand the mechanics of a lock. Perfectly engineered.

Excellent concept... Good quality..

Building it was good and works good enough to show the principle. But it got fungus and mould on it too soon so had to throw it away hence the three stars. For its price its a good buy.
