I like to keep my tires tweaked up to 36 psi cold pressure, and since it will be necessary to remove the sensors to add air each time, I think I would just forego the use of the anti-theft ring. The inconvenience of using a wrench to loosen the ring, then screwing the sensors off and on again frequently is not very appealing to me. I also wonder how really "locking" the anti-theft rings would be. It looks like a firm counterclockwise twist of the sensor would loosen it from the ring pretty easily, but maybe it works differently than I think.
With the price of $80 for the whole package, it doesn't seem like a thief would bother with stealing just the sensors, which are useless by themselves, but I suppose it could happen.
