3. Limited torque range: The Wera FNOB nut setter is only suitable for use with nuts and bolts that require a specific torque range, which may limit its versatility for some users.

4. Requires calibration: The Wera FNOB nut setter requires regular calibration to ensure that it remains accurate, which can add to the cost and maintenance requirements of the tool.

If you frequently work on complex projects with fine threads or hard-to-reach nuts and bolts, and have the budget for a high-end tool, then the Wera FNOB nut setter is a worthwhile investment.
