Had anther brand that was corded. It was awkward to change out blades and when you did the screw that held them in would vibrate loose. I saw this on ebay for a price that was far less than even the big box stores. I bought it and it came very quickly and well packaged. I actually ad to use it a two days later to cut a a small opening in the top of a cabinet that had very little room to work with. Did a great job.
