This has got to be one of the most used tools I own now. I don't know what I did without it. I had my doubts about the durability and lifespan of the battery along with the power for only being a 12 volt but I have to say it more than surprised me. It has very decent battery life and has all the power you will need. With all the attachments that are available it is truly a must have tool for your toolbox.
Got this in a combo kit and am very glad I did. I already had a corded one and it was very noisy and therefore did not use it very often. This one is no where near as noisy which is awesome. I use it frequently and it is a great little saw. I love the quick boost for it because that means it is not down for hours recharging. All in all a great little multi tool.
