Man, he's redesigned that thing about a hundred times (that an exaggeration, for you Edge-heads that are going to jump on me). Since my car (or my cultured marble) never tries to pull my pad off my machine with 100 pounds (or even 50), I can only guess that people are slinging their Edge pads off like Frisbees.
It does look like usability improvement, but it looks like it increases the length again; didn't we go through the shortening mod? I can't remember how many times I sent my adapter back and I haven't even used the thing yet (yes, I have too many pads along with everything else

)
Edit: I was referring to my PC adapter. Looks like the rotary adapters are longer, and since this new one is rotary-only, it seems the length isn't an issue. BTW, did the Edge adapter/pads ever get cleared for the
UDM?
