Bought this new along with the tw-2.2. They arrived un-calibrated. Following the manufacturer's calibration instructions was ineffective. Instead it caused the handle to come loose. The glue felt cheap. I'm disappointed and frustrated. 1. Park Tool YouTube videos always show well calibrated beam torques. I couldn't get this with 2 wrenches bought online with no proper way of achieving calibration. 2. Why wouldn't a tool manufacturer making precision tools also make calibration tools and apply them to his precision tools before selling to the customer? The customer is concerned with what he needs these precision tools for, not the new condition of these 'precision' tools.
