Abus is a good lock as lock as their is a code card, otherwise you might get one that everyone has keys for.
It cannot be picked, would take a lot of effort for someone to use a grinder, anything else isn't possible. Make sure there is a code card with it or it only is single keyed.
I didn't immediately understand that the little plastic lock cover swung open and I tried prying it off (unsuccessfully). Key seems to wiggle too much to feel assured of security to picking. Time will tell.
