The Peterson Otoscope and the HUK fibre optic flashlight both try to help you look inside a lock. One does a far better job than the other, and is far cheaper. The cheap USB so-called endoscopic borescope inspection camera gets a dishonourable mention as well. It's junk.

The Medeco M4 is a truly excellent mechanical lock, and I think a very important one for Assa Abloys product offerings in North America. Picking it is an interesting experience in that it picks slightly differently every time. Not because the tolerances are super close (like say an MT5+) but because the inherent randomness of the rotational Biaxial pinstates means that you sometimes end up with an easy problem to solve, and sometimes a harder one requiring more steps. Binding order can bounce between top pins / rotational keypins / finger pins and in this instance I got a lucky roll of the dice.
I have a LOT more to say about this lock and will do a proper review video which Ill link here in due course.

The BKS Helius and Livius are great locks to pick - unusual and fun. In this video I teach you everything you need to know to understand how they work, and how to beat them. Plus one lucky bastard will take them both home.")

I have no hesitation in saying that this is the worst high security lock I have ever seen. My guess is that Abus really cant believe they allowed this thing to come to market, and are trying to bury it as fast as possible.
With massive thanks to Michael in Germany for letting me pick this lock.")
