What is Reddit's opinion of Altor SAF Lock - Angle Grinder Proof Bicycle U-Lock?

From 3.5 billion Reddit comments

Pretty much any standard lock will be able to be defeated with an angle grinder extremely quickly. This includes u-locks and the popular abus bordo folding style as well.

There are a couple of fairly impractical options that exceed these though. The first is the Kryptonite New York Fahgettaboudit, which is a super heavy duty chain lock. The chains are very thick hardened steel, designed to be difficult to cut through. That doesn’t mean it’s impossible though, as there are many reports of thieves with moderately decent angle grinders cutting through them very quickly.

The only one that’s really angle grinder safe is the Altor SAF. It’s expensive though, and almost comically large at 13+ pounds. Probably something that only makes sense if you leave it locked to your most common destination. It’s thick enough that it cannot be cut through with a standard angle grinder though, and is probably the only lock that really qualifies as safe from that type of attack.

If a thief can’t cut through a lock though, they will cut through whatever your bike is locked to or a part of the bike itself. The realistic solution is to just get appropriate insurance and a reasonable lock used in combo with a good locking strategy that will make your bike less attractive to thieves. I use the kryptonite evolution that comes in a combo with a cable that I connect to the front wheel.

That lock is really expensive and heavy, but in testing it took 5 angle grinders to cut through.

And in particular, if you're willing to ride around with one of these https://www.amazon.com/Altor-SAF-Lock-Grinder-Bicycle/dp/B08779BY8D you're probably good XD
