I came across this independent site quite by accident, the other day and am delighted to see some other opinions about our signature product Bilock.
"Medeco locks are currently used in over 75% of the US high security market, with few users knowing that they may want to avoid Medeco locks. While worldwide their high security market share is much lower, in the US they still are the predominant high security lock. Unfortunately over the past few years, several vulnerabilities of this system have come into light. While the system certainly offers more protection over a standard pin tumbler lock, in the price range of Medeco locks there are far better security solutions. Keep in mind that most of the vulnerabilities listed here apply to standard Medeco Biaxial and M3 locks (like deadbolts, and padlocks) and not to their line of cam locks, which utilize a different mechanism and still appear to offer a decent level of security (as long as they are not overly master keyed, and some key duplication issues still exist)."
"If you are looking for something that offers more pick or force resistance and the many benefits of a traditional high security lock we currently recommend Abloy and BiLock. Both are very good high security locks, with the Abloy Protec being one of the few locks that has yet to have a documented method of picking, bumping, or imprisoning since it came out in 2001."
