Children ages 3+ love it. The "best" age is probably 5-12.
Parents and Grandparents will absolutely LOVE building things with their children & grandchildren!
This has an advantage over LEGO blocks of not having small pieces.
You might be wondering, “is my 12 year old really going to find this interesting?” From our experience and feedback, it’s a resounding “YES!” Kids are waiting for opportunities to open their minds, creativity and discovery with active play. Technology is usually a big part of a child's life from a young age and it's difficult to find "toys" to spark an interest in pre-teen developing minds. TubeLox is invigorating for these young minds. At a very young age, children can play with TubeLox and start forming desired pieces and shapes while discovering how to put them together easily. This toy is easy to put together for all ages, unlike very small connector type toys.
