Matt, You are confusing Chicago Pneumatic with Central Pneumatic. This is a low life attempt by Harbor Freight to entice the unwitting into buying their low priced second rate tools instead of the higher quality real CP tools. The fact that you fell for it is just another example of the unfortunate fact that the scam works
The really bad part is that for a "cheapo" tool the Central Pneumatic does ok for what it costs and would probably sell anyway without resorting to scam type sales practices. But beware! Central pneumatic is a cheap second rate tool and nowhere near the quality of the real CP which is a professional quality tool!
