We bought this saw because our little one (4 years) absolutely wanted something for her birthday. To date, we are quite satisfied. I think this chain is certainly not worse than other models of this kind, there is something for children on the market. The blade forms a necklace with beads strung Silberen that naturally rotates like a real chainsaw. For this purpose a motor sound is heard (luckily not too loud). With us, the part now been two weeks keeps the stress caused by two children by (4 + 6 years). However, the same time gave away drums found more favor. So if a child is necessarily something wants, can buy this saw. Educational's certainly is not.
