when I bought the machine 4 years ago I was absolutely delighted small and fairly easy, but to get strong enough to actually all small thing that came before the saw, and that was not enough. The more I am stunned by the fact that the chain tension is held by a 1 mm thick plastic disc in place that went punctually broken after just 2 years, it is clear, is not so much thicker than a yogurt cup and made of hard plastic, the disc is crumbled downright and since then the chain will change each time to a half-hour Gefriemel. If Makita here took a cozy little metal discs I would dote the machine, but it gets me only 2 stars because the chain tension is threatening to fall out when changing and then I can throw away the machine.
