I have just had my oxygen eMate nicked from a Kent train station it was fitted with two krypton locks, cable and d lock both gold standard. Talking to the station people they say it has happened before the thieves use a cordless angle grinder fitted with a diamond stone cutting wheel, they wait for a train to be pulling in and strike quickly. I am insured and it has been reported to the police but for my next bike I will use two Kabrus alarm locks. So the first is screaming while they try to cut the second.
