It appears that S&T has gone to the $#!&ER.... heck, why would anyone even want a Quark anymore, they are garbage compared to the MMM, and they cost twice as much.
Well yeah... if you can get a MMM to stay working.
I feel your pain, I have sent in 3 quark escs for service, 2 of mine and another member's esc...
Sent to Korea, but no reply to email and no confirmation that they have received them. Global tracking is also not working on line, so I may have to call the PO and see whats up. I hate shipping stuff out of the country...
