Any Brompton users of the current generation ("Superior") MKS Ezy clipless pedals, whether platform or cube styles?

I'm considering them for my Brompton, but a couple of posts from a while back suggested problems with pedals detaching themselves in use. These might relate only to the older (original?) Ezy mechanism. My motivation for clipless is to pedal harder securely, and having to baby them in case they detach would defeat the purpose.

I put the bike into a hard case often and don't really want to have to carry a pedal wrench, so non-folding pedals of any flavor aren't an option.
