Well, I have three of those on my desk right now, but to be honest I
haven't had much time to test them. I'm trying them out for basic L2
switching, a bit of routing and a small amount of EoMPLS.
Specs & docs look good, pricing seems OK, but as "experience" with the
box goes I've only configured an address on them and performed a
software upgrade.
If you have specific questions, don't hesitate to ask, perhaps I can get
the answers quickly.

Jeroen
