Better than Legos!
This is a great construction set for young and older kids. The pieces interlock easily as well as pull apart easily when you are ready to disassemble. They hold together well and are flexible enough to make angles as well as curves. I have two girls, ages 6 and 9 and both enjoy making not only mosaics, but multidimensional structures. My children hands down agreed these are better than Legos. I think younger children would have fun as well as older kids. In fact, my husband and I both enjoy making things with these. The 600-piece set is a nice size. I also like the educational components of this toy--playing with them increases problem solving/reasoning skills and builds spatial perception, among other things.
