I installed the old design on 5 bikes, and i cracked one non drive side arm at 6 or 7nm. Racework is largely useless to deal with. They made so many mistakes in my order with them that i can't remember the exact count. Beyond the cranks, i bought 12s chains from them, they sent me 11s, the bar tape they sold me is the absolute worst i've ever used, and more. They refused to warranty anything, including the crank arm even though it was low torque (they dont tell you what torque to use, btw), but i managed to buy a replacement one for cheap enough - abnormal, but at least i still have 5 cranksets to use and not 4, for now anyway -.
We've put around 5k km on all these cranksets so far, i'd say. to avoid cracking more crank arms, i'm using 5nm and an obscene amount of threadlock. It's been working.
Either way they updated the non drive side design.
I wouldn't recommend them, goes without saying, but to be fair, i'm happy with the cranksets as long as it's not broken - kind of like i'm happy with my ltwoo er9 when it's not broken, the problem being that out of 5, 2 broke for no reason -, and their 3d printed saddles are nice too.
