Simple single-value torque wrench with replaceable hex tip. Would have been nice to have multiple metric Allen wrench sizes - they're not too expensive to include. Only supposed to be used for tightening, not loosening.
I tend to over tighten bolts (it probably has nothing to do with 5 years USMC and 30 years working in the woods). This tool lets me tighten bolts to the proper torque without adding to much torque until I break or strip the bolt. Since these wrenches are not adjustable make sure you get the correct wrench for your job.
bought this tool not really knowing much about bicycle mechanics, i still don't. but, i do know that a torque wrench that does more than just one bolt is a much better idea. if you only need a torque wrench for one bolt buy this one
Recently took the Park Tool School class thru REI and instructor showed us this tool (Orange N5) which pre-loaded 80% of fitings on my all carbon bike Madrone 5.2 which is 10 years old now. He said its the most used tool in their shop. All 6 of us in the class was excited about time savings and easy of use. Worth every penny.
