There are two models, one with a 4,5-inch blade (#UC120DWD) and one with a 7-inch blade. Durable, lightweight and effective, the Makita cordless chainsaws are getting positive reviews all over the web. The Makita costs a little more than for example the Ryobi, but can well be worth the extra money. If a gas powered chainsaw feels like overkill for what you need done, the Makita is a very good choice.
