Let me start by saying that I am a cable loader. All my power tools come with a porter cord. I do a lot of home renovations so the Porter cable is great for my needs. I am disappointed with this device. The cartridge is rusty when open. I couldn't close the chuck to insert the blade. I don't even want to talk about how that happened. But I was disappointed with the quality control and/or packaging of this device. I was in the middle of a project and couldn't wait for a replacement. I had to increase the torque to the max and twist with a lot of effort to get it loose. That's when I discovered the problems. I have since cleaned and oiled the parts and now the drill works. It's too early to talk about longevity or longevity.
