This is the best company to buy from. I had a shipping problem which they cheerfully corrected. Great company Great toy

This is a nice set; however, I'm glad we got it on sale because I think it's a bit expensive for what it is at full price.

I got this for my grandson on his 5th birthday. He spent over 2 hours putting his imagination to work building various multilevel structures and explaing what they were. It was a big hit. The hammer is very effective and easy to use. I would definitely recommend this product to help kids use their imagination and learn building basics!

This was a huge hit with my almost three year old grandson. The pieces were easy to manipulate and fit together in multiple ways. Two hammers mean that his 14mo old sister could join in and the wrench was easy to use too. Thinking of buying a second set for even bigger constructions.

My 4 1/2 year old twin boys each got one of the 100 piece sets for Christmas and they have been playing with them constantly! These are the first toys they go to each morning. My sons are having a wonderful time building their own creations and using their imaginations. I can't say enough how pleased we have been with these so far!

My students, especially the boys really enjoy working with this block set. The blocks are very sturdy and stand up to wear and tear. It would be nice to have a few more tools to go with the blocks, so that more students could use them at once. They can be somewhat difficult to take apart, but most of my students have been able to do so with little assistance. Overall, my students really enjoy building with these blocks and I have been very pleased with the product.

My students enjoy the Big Bolt Construction Set, but there isn't enough tools included for groups of children to enjoy this set together.Also children usually need a hand to take apart their projects.

My only complaint is that is does not come with more tools in the starter set. There are lots of pieces, so more children could use it at one time if it came with more tools.

We received these as a "prize" in a class we took on manipulatives and motor skills. The children seem to like them, and some children can be very creative (but some seem to be stuck on cars, since there are wheels). I'd like them better if they were wooden instead of plastic. They are durable and easy to fit together, but lots of kids ask for a screwdriver (not included).

We've had this for 2 years now and it's still in great condition. My five year old loves it and I plan to pass it down to his brother in a few years.

I have been in day care for 14 years and I have bought two of these classroom sets. I have children of all ages and it keeps them busy for hours. This is the first thing they grab to play with. The things they invent up is limitless. Guitars, robots, the list goes on and on i love them. I highly recommend it.
