IMO, those locks are rubbish. There is no reason to go from analog to digital when it comes to bike locks. I don't want to depend on bluetooth in order to unlock my bicycle. The wimpy alarms most of those types of locks carry are silly sounding and wouldn't really do much to deter theft. They have an option of letting you send other people an access key to unlock your bike for you - who even shares their bikes with random people?

Do yourself a favor and save some money and just get a tried and true heavy duty ulock from a proven brand.
