Review on Venzo 1/4 Inch Driver Beam Torque Wrench Set - Precise 2 to 10 Nm Adjustment - Ideal MTB, Road Bike & Motorcycle Maintenance Tool - Complete Kit with Bits - Essential Carbon Parts Tool by Ronnie Polk

I bought this looking for a simple, accurate and reliable bolt tightening tool for my MTB carbon frame. First: There is no certainty that it is tightening to the desired Nm. It has a pressure gauge, but this tiny little tool isn't certified, and when I turned it I was nervous that it might not have been properly calibrated, and I was about to over-tighten my screws. and didn't pull it out. I'm glad the Revain return is so convenient and quick - I sent it to UPS and they credited it to my account the same evening. I put credit and a few bucks more on a Pro Bike Tools 1/4" torque wrench and it works great. Don't overdo it with a torque wrench or you could ruin an expensive carbon frame bike!
