Locks that work

Thieves were able to cut Simplicissimus's decent U-lock twice with not much noise, wonder if it was the 54 model which gets great reviews:

It was secured with an Abus Granit X Plus U-lock to a proper bike post, around the middle of the frame. The U part had been sawn through in two places very cleanly. Obviously the thieves came prepared - almost certainly local I'd guess. Though out of visual contact I was very nearby yet heard no loud noises - any ideas?

I'm skeptical of the times they say it takes to cut u-locks with an angle grinder. I cut a link out of a Sold Secure Gold **Secure-A-Bike 10mm Chain **using a cheap angle grinder with a metal cutting disc and it took less than 10 seconds to do two cuts, it was good hard metal as a decent hacksaw hardly made a mark on it.

BikeRadar said: Moving onto the power tools, our angle grinder did cut through the Xplus in 59.8 seconds.

Tmysko does it a bit quicker:
