I was going to go halves with a golfing buddy - he went to buy it, tried it out with some intentionally garbage swings - and it wouldn't break down. Try before you buy!

Update: I had a chance to demo the Medicus 2000. This club is best used with a spotter, or with a camcorder taping your swing.

The club will breakdown in any position that is off plane, or moving too quickly (it breaks if your takeaway is fast).

However, if you make a compensating move, the club will realign itself (making it possible to hit balls). The downside is that once the club 'breaks', it doesn't stay broken, so without said spotter, you can't tell where you're breaking down.
