This saw is a light and powerful piece of machinery. It is easy to work with and great to be able to use it anywhere - in my attic for example - without the need to stretch a cord from hither to yon. Unfortunately these saws are not sold with batteries and the batteries cost around $100 each. I already had a Hitachi D series Cordless Drill that came with two batteries and so this wasn't a problem. As with all circular saws the blade guard is a pain. The other problem is one with all saws as well - they are made for right-handed folk.
