We've had a 12yo and 5 yo successfully implement some of these fine upgrades. It has been a very nice addition to our grown Snap Circuit collection and can implement with other kits for a variety of more complicated patterns. It has been a lot of fun for all of us. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A great addition! *by A***S on Reviewed in the United States on December 15, 2012* My career was as an electrical engineer. But, I started in electronics at age 5! At 12 years old, I passed the Novice class ham radio license. I was the first ham in town and I had no help. By 13, I had passed the General and Advanced classes. I designed many projects, including a one tube transmitter that worked the worl.The thing that stops many people, especially young children, is soldering. This kit doesn't require that, nor do any of these series. My nephews loved the basic kit so much that they stole batteries from TV remotes, etc. so, in addition to this upgrade, I bought the battery free A/C adapter.This kit expands the number of projects and the knowledge of the children (or adults) who use it. I want SO bad to play with this! Maybe Santa will get me one! Buy it! Even if you bought the first kit, you can add this one. Or, do as I and buy the next kit for a birthday, Christmas or just because it expands a child's knowledge in this strange texting in another language, spending all day looking at a computer, video games, etc. It is a fun way to LEARN! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great product and support! *by J***D on Reviewed in the United States on July 5, 2014* My 7 year old loves his Snap Circuits. He received the SC300 as a birthday gift and immediately wanted to upgrade it as he saw that their were more parts available. They have reached almost the same status as Lego! Yes, as mentioned, some experiments are duplicates. However, with the Student Guide, it offers great education and play.We also purchased the power adapter (no more batteries). Then after frying a few transistors, we purchased him the Student Guide to teach him more about the individual parts (and how not to fry them).Elenco has a FREE lifetime warranty on the pieces of the kit for individual consumers! How awesome is that. I assumed my son would have to buy the parts he fried. Nope. Elenco has done an excellent job assuring that kids will be able to enjoy their kits and not throw them out after frying one piece (like other companies kits).
