“This is my NT6210. We are just out of one of the worst storms in living memory here in Ireland. This saw worked for 3 days almost 8 hours a day. My first comment is this saw is very well balanced and constructed. My second comment is it is very economical on fuel. Very happy to recommend this saw to anyone who asks me. Blade is holding its edge very well. Craftop is the Toyota of chainsaws.”
