"Age 13-14. He has three of these books. He loves them. Had them for two years now. Still finds things to try." Natalie Ritz said.
"Bought this for my 11yr old son. He loves it! It you give it as a gift (and it's a great gift!) Make sure to throw in some clothespins, tape, rubber bands and other goodies. This is a great solution to "I'm bored "." Lavery6 said.
"Our 9 year old loves this book. He's constantly digging through drawers to find the parts to make one or another of the projects. Some are very quick - no more than 15 minutes..others longer and more detailed. He even used it at a show and tell/talent show showcasing 3 of the weapons he made himself. Nothing watered down - these are legit catapults, spit wad shooters and more. I'm thinking this would be a really good gift for someone who works in a cubicle and needs to blow off some steam just as much as a 8-12 year old." JustOneGuy said.
"This is an amazing book! I made a cool slingshot and I love it!! If you are into weapons I completely recommend this product to you." Dylan said.
"Bought this for my 10 year old son who loves it! He has successfully made many of the weapons and has had a lot of fun doing so. This is a great alternative to spending time staring at a screen. I ordered multiple books to give as presents and they are always very well received, both by boys and their parents. I do get a bit annoyed as my son keeps taking apart pens and pencils to use while building the devices but, I put up with it as I think he is learning while having fun!" a busy mom said.
