Review on PRO BIKE TOOL Adjustable T Torque Wrench for Bike Maintenance - Road & Mountain Bikes - 4, 5 and 6 Nm - 1/4 Inch Hex Driver - Home & Roadside Repair by Andrew Lyons

The knob on top is so hard to pull to change 4.5 or 6nm. I gave another try today and it completely stopped spinning (got stuck). I think I had a broken instrument. Another thing to mention, the included bits are too short when attached to a wrench and difficult to use in tight/narrow places, you will need to purchase longer bits or a 1/4" hex wrench extension. Update 1: Good news, after emailing pro bike tool support they offered a full refund or replacement. Replacement is on the way. I will test the new one and then update my review.
