I have just had another great experience with Park Tool.
I "Like" their page on Facebook and get updates. They have some contests where you simply comment or share for a chance to win a tool. Earlier in the summer when they released the CT-3.2 (newly updated chain tool with a moving shelf) I won one of them from them. I already owned a CT-3, but having another meant one could stay in the shop and one travel.
I was using it last week and I felt like the movable shelf was a little loose, I had seen nothing in the instructions to address the new shelf, so I grabbed an allen key to tighten it up, the allen head broke. Crap!
I snapped a photo of the tool and e-mailed it to Park Tool. Before I sent the message I checked the website to make sure I was using the right terminology when I noticed a note about the new tool saying that trying to tighten down the shelf could break the tool, I took that as a disclaimer, but I sent the message anyway affirming that I had just seen the warning and it was totally my fault that the tool broke.
This was their reply:
"Please keep the “T” handle as a spare, and recycle the casting.
Your replacement will ship this week."
Followed by a FedEx shipping confirmation.
AWESOME TOOLS, AMAZING CUSTOMER SERVICE!!!
