Review on Bikehand 1/4 Inch Drive Click Torque Wrench Set: Ultimate Bicycle Maintenance Kit for Road & Mountain Bikes, Motorcycle Multitool with Allen & Torx Sockets, Extension Bar & Storage - 2 to 22 Nm by Jeff Wieczorek

The hex heads seem to be well made. I've been waiting to get this kit to install a Renthal carbon handlebar on my new mountain bike. I really don't think this torque wrench is accurate on its own. It seems like maybe 2 nautical miles? I had to tighten some hex bolts to 5Nm but ended up reducing it to 4 because it felt too tight. There's a red arrow you can adjust to set the torque, which appears to be off-center and made in China. Special Note: If you're using this wrench to tighten a reverse thread, look elsewhere. It only threads in tight mode, not in the slack or reverse thread direction. If you can check the accuracy of the torque and adjust your wrench to compensate for the inaccuracy, you should be fine. If you have a quality carbon mountain bike that you know doesn't come cheap, invest in a high-end torque wrench from Snap On, Shimano, or a park. I don't normally buy Chinese tools, but I needed a torque wrench that can be used for low NMs. My other torque wrench doesn't run as low. I plan to keep this set of keys, love the 4mm contour it came with.
