My neck and shoulder are messed up (along with the rest of my body), so a mirror is pretty critical for me.
Like you, I absolutely love the Mirrycle Mirror- it's in the perfect spot- it's always pointing exactly where you want it, you know where it is and it's easy to adjust- but it stays put. You don't need to move your head to see the mirror, you don't need to turn your head to look at the mirror and figure out where it's pointing to direct it where you want it.
A few years ago, I went through a bunch of mirrors- My favorite mirror is an old Axiom that clamps on with a rubber strap. The Eyelink is OK on the right lever, the Blackburn is OK.
Here's a mirror thread from a few years ago:
