Mine looks identical, except the branding, mine's 'Giant' Not really sure how good it is
Bought it a couple of years ago when I got my first carbon bike. This summer the seatpost tube cracked & after the supplier initially arguing that I had overtightened, I got a new frame. Collar stated max 7nm I set the wrench to 6nm & a week or so back the carbon seatpost on my ti cracked right at the top of the tube
Hoping to get the wrench checked/calibrated next week. I'll let you know the results, ie how accurate it is
