I got this for my 4-year-old for his birthday and the product fits him well. He likes buttons and lights, and I love the opportunity for him to get familiar with his numbers. I love every time he informs me the time is "L5B" (7:58). We sometimes sit and count the seconds together (he's still sometimes forgets 15 on his own). We've even built it into his naps/timeouts ("quiet time will be over when this number is a two"). He has such a raging enthusiasm for his numbers/letters - it's great to have a tool to try to keep up with him!
