Your reviews are always the best, thanks for this super affordable security feature. I think this would be a great second disc lock, move the first to the rear disc and leave this one in plain sight for the layered approach you mentioned.

I recently got the XX14. It feels pretty solid and has a much better, smoother locking mechanism compared to the little XZZ6 I had before. The optical alarm system isn't great but it does the job.

Great review of this lock, kind of an improvement over the older version but still needs improvements lol. they can't seem to get it completely right. lol sensitivity is way off. They should have tested much more. They should hire you guys lol

I've got the XN14 or XN15, I'm not even sure, been using it on 4 different bikes for 7 years now, no issues, just changing the batteries about once a year.

Good data point, thanks.
