Hey all,
Just wanted to chime in with my excellent excellent experience with
the SER-001. It was very easy to install, and I am thrilled! I have the
"case bulge" syndrome as well, but I don't see any real problem. The
port cover still closes flush. I made sure just not to retighten the
screw in that area as much. I can't wait to purchase the audio adapter
from you, Dave!
Thanks
Brad Tober
