Kidding aside, I bought my set close to 10 years ago, and everything still works. I've added batteries so I've got 4 in rotation and two chargers, and I've worked all day and never run out of juice. Plenty of torque for just about any job, and I can't even count how many times I've knocked the drill driver off of high places and had to climb down and get it. Nothing has broken, needed repair, or fallen apart.
Plus, they've got a TON of tools as part of the C3 platform.
