I agree that we do NOT need to waste money on $120 locks. It's all about Stradgedy. U locks are a big "key" to all this as are thick cable locks in ADDITION to the U locks. WHERE and HOW you lock the bike is another "key". In a well traveled area so people can SEE if anyone is attempting a theft. If someone is using a grinder to open a lock then MORE THAN LIKELY they should NOT be using that grinder. REPORT those kind of people.
