My 40 year old husband had a BLAST playing with this and doing projects from the instruction manual plus his own circuits. Kit was purchased for a Cub Scout troop - who may get to use it when he decides to share ?This gift was a huge hit with my 5 year old Grandson and both of his parents. It’s very educational and easy to master and put away the different parts. Highly recommend this!!!Got this set for my 8 yr old son for his birthday. He had played with a set before so I already knew he would like them, but as soon as he opened the box he couldn't put it down. There's so many things to create he has yet to get bored. The 12 yr old neighbor kid came over to okay and I didn't see either of them for a few hours except to show me what new noises or circuits they discovered. Great for a variety of ages. Engaging enough for older kids and easy enough for younger kids too.If you're wondering what to buy your child this year that is not another toy or video game, consider Snap Circuits. Elementary schools in my area have introduced them as part of their STEM curriculum and they have been a hit with the students as they are able to create all sorts of projects, including alarms, fans, lamps, AM radio, doorbells, special sound and light effects, etc. I will compare it to Little Bits and Lego Mindstorm below.There are materials and training out there to build more elaborate toys that could potentially get your child a Science Fair prize, but if you're looking for something affordable that doesn't require an advance degree, allows kids to have fun on their own and spend hours tinkering with, you'll soon find that the Snap Circuits 750 sets is the best investment. It is the one my child's school picked in the end for ease of use and because - let's face it - kids love it. A Top 10 Educational Toy award and a 5-star overall review speaks for itself.Don't let the nondescript look and fancy name fool you - this is a high quality, five-star rated toy, voted one of the best of the year. You can buy smaller Snap Circuit sets with the individual manuals, but the price overall will be higher when you buy all five separately. Get the whole set instead - the SC-750 set is a bargain for the hours of fun this will bring your child and your family for years to come. This set includes the 5 easy-to-follow manuals of the smaller sets and all the parts needed to build 750 projects in all, in a sturdy carrying case to hold it all. It's for kids 8-15 but grown-ups love to help as wellThis SC-750 set grows with your child. As a learning tool, the projects are meant to be done in some sequence, with each one explaining a part and what happens if you move this or that - at least in the beginning. We started working on the Jr (100) set which is the pink manual (1-101) when my son was five and he was able to do it with our help. Every step is explained, once you learn one project you move to the next and see what happens to a siren when you add a resistor, for example. The descriptions are kept short and to the point - for example, that the resistor lowers the volume.One reviewer wished each part of each project was explained in detail each time. As one project builds on the knowledge from a previous project, it's impossible to explain what happens with each part in any one project. This would fill the page with tons of text. Rather, it's a gradual learning process and it's assumed that earlier projects have been done.Four years later my son still loves it but is able to do it on his own, and is doing projects from other manuals. He can skip ahead too as the diagrams clearly show how to put all the parts together - though he might miss some explanations about the "why" of using each circuit part in a particular project if he doesn't do them in sequence. Not a big issue at this age where assembly-type toys with lots of parts are the norm.My now nine-year old considers the R-750 set to be - in his words - awesome. Seeing how each varies intrigues him to no end. He's still fascinated with the set, more so now that he's also using them in school.I've also had the opportunity to see other STEM toys in action. A month ago, Barnes and Noble hosted Mini Makers fairs in stores nationwide and one that was featured was Little Bits. It is probably more along the lines of more traditional circuits, where small components are put together to create alarm clocks and moving parts in legos. It is also exorbitantly expensive. Fortunately some libraries are investing thousands of dollars in buying these so you may soon be able to find them free of charge near you. It too ends up creating gizmos and gadgets, but for a lot of $$.Today I covered another STEM event at a library, this time with Lego Mindstorm. A teacher helped students for two hours to build a Lego robot, starting with the base Mindstorm unit, programming it on a computer, setting up parameters for instructions to make the robot spin, turn lights on and off, etc. This class was free but if you decide to buy it on amazon, a Lego Mindstorm Kit is very expensive and only lets you do a handful of projects. Now the big "BUT" kids have a hard time doing these on their own which is why schools are bringing teachers to train them and companies - not schools, at least in my area - are doing after-school classes and summer camps just to learn how to use this Lego Mindstorm. If the teacher leaves, the kids are left with a bunch of technology they don't know how to use because it can be so complex.In all, either as an introduction to circuits or simply as an assembly toy, it's a winner.She loved it and created more on her own.This was a birthday present for my 6 year old grandson. His dad is very tech savvy and wanted to start his son with something he could learn and grow with. My son who is in his thirties was explaining how it works to his adult friends and my grandson. They all seemed to enjoy learning.Our 8yr old boy is absolutely in love with this!!My Grandson and Granddaughter like it age 9 and 7This is an excellent product for enquiring minds. I have purchased both the junior set and the electronics discovery kit and have been impressed with the quality of both. The kits are strong and durable and my grandson has had endless fun building the various circuits. He has been able to use the knowledge he has learnt to help with school projects. Snap circuits make learning fun and are a great educational tool. I would definitely recommend and will be purchasing more products in the future.This was the largest Snap Circuits pack I could find and as such was quite expensive but good value compared to buying smaller sets to add together. Purchased for my son turning 8 and he has had SO much fun working through the book, creating each project on his own. Each one is slightly more complicated than the last and he takes great joy in presenting to us what he has created, be it something solar powered, a moving propeller, a light circuit, one with sounds. The fact the pack is so big means there’s no time to get bored and to have “done it all”. Excellent buy.If only schools had the money to use these sets in classrooms. They are just fantastic with plenty of easy to understand projects perfect for little fingers. My daughters always have a snap circuits set on their birthday/christmas list and I wish I could use these with my pupils.With no doubt, this is the best toy we ever had (P.S. I am a mum of 5 & 7 years old boys and a "bit" obsessed with educational toys).It was very risky from Santa to bring a Christmas present that was not on the list but it was worth it - SNAP CIRCUIT is far the favorite from them all. Oh, and one 20 year-old was very jealous for them... ;)My 5 year old can play with it for several hours in a row, and sometimes all he needs is recognition from us when something has been created. There are endless projects to make from instructions or create own ones. They love to dance by the music coming from self made FM radio, they love the flying saucer experiments as well as create own ones.Boys love it so much that they just put together their own pocket money to buy the Light kit. At least now they will have separate boards and some main spare parts doubled and will be able to work side by side as well.The only con for this toy is missing opportunity to buy specific missing parts separately for additional projects, e.g. Magnetism, Light, Music, Eco, etc. There are limited options to order spares from official US site but shipping is $35+ and then it is not worth it, the whole new kit is almost cheaper (but hopefully it will soon change).Although when the original box will rip apart there will be one more big investment of £48 for Custom Storage Case to make - with limited space only for this particular kit. My 8 year old granddaughter had been doing "Electricity" at school building simple circuits and had loved it so this looked perfect for a Christmas present. It proved to be just that, she now uses the Snap Circuits on her own and runs in to show her mum and dad what she had done with great pride. She was also able to predict what would happen and to fault find when she had inserted a component in the wrong way round. An Excellent purchase.
