The high-trust caveat is sharp: OutdoorGearLab found that with the thinnest shackle of Kryptonite's U-locks (12.7mm), the Kryptolok Standard was the quickest and easiest to cut, going down in about 10 seconds with an angle grinder. r/cycling commenters echo that it's a step up from a cheap cable but suggest stretching to the $50-$60 range for something tougher if the bike is valuable.
The consensus is that this is a sensible deterrent for mid-value bikes in lower-risk areas, where its job is to make a thief skip your bike for an easier target, not to survive a serious tooled attack.
For the most part they are much better than the cheap alternatives, but the one you linked to isn't even strong enough in my opinion. I would go ...
It's probably better than a cheap cable, but not much else. Short answer, no. Look in the $50-$60 range of locks for a decent lock.
