What makes people think they are applying the correct torque with a quick release lever?
I get the convenience but actually the only way to accurately measure torque is with a torque wrench...if your into that...
I have these on my road bike. No issue so far other than that the conical split washer under the bolt head had fallen off in the box during shipping and I didn't realise it was needed. Tightening up without that washer crushed the bearings a bit so it had to be backed off which felt wrong until I compared it with the rear and realised the washer was missing. Fortunately I had not yet recycled the box!
But there is no correct torque published for QR, other than an unwritten ‘Hand Tight’

Thru-axle QR and stealth axles work in different ways. The 'correct torque' for a thru-axle QR is just enough to remove any play - the pinch of the (correctly adjusted) cam is what stops it unwinding.
Do it up just tight enough so it's really bloody hard to close the lever, then ain't no way its working itself loose. Worked on 9mm QRs since the 80s so why should 12/15mm ones be any different 😀
(not completely serious, btw)
8mm one on my scandal rear end was a pain and a risk as my multitool at the time didn't have an 8mm key on it. Changed it for a ztto 6mm which was made of cream cheese. Now got a brand X ok one with a lever.
Overwise not hav a problem on my CX bike. Wheels off in the car for races and cleaning multiple times a week.
Given the choice I'd go for the Canyons ones though. Look a bit stealth as the lever tucks away nicely inside the axle. Best of both worlds.
I never torque anything though. Gentle, nip it up, firm, tight, put your back into it are my settings?
How tight are you people doing these axles up to round off the bolt!
Steel Allan key in a poorly fitting alloy hex socket will round. It's not just the torque. See Thomson stem bolts.
BTW these are standard use in QR hubs for aero gainz. Removing two QRs saves weight and a small Allan key in the pack is easy to carry.

Cammed quick releases are different to be fair, the small lever means you have to work very hard to cause any damage (unless it's one of the terrible rockshox rear maxles with the snappy levers) and the force isn't rotational, so it's hard to meaningfully overtorque. And the cam makes it less likely to come lose. In some ways it's a superior option, it's just that it's also bulkier and has more moving parts.
