The only problems I have had are with shipping.
DA uses Airborne/DHL which once in your local town
is converted to USPS. It is a horrible system. The
companies are always pointing fingers at who is
at fault for you not getting your package... and
DA is like, ok, we'll refund your money, but we sold
out of that LE 2 pin, so there is nothing we can do
to get you that pin.
I've never had to have them refund a non-delivery,
however, I have had a rather expensive load (3
prototypes - $100.00) take well over a month to arrive.
I've heard they are getting better... but I haven't
really seen it. For the price they are charging for
shipping, they should overnight the packages to you.
The boxes are huge, and light as a feather... coming
from working at UPS, I KNOW it wouldn't cost nearly
as much as they are charging.
Because of this, my feedbacks have been positive,
however they all read: "Nice pins, great quality,
but YOUR SHIPPING METHOD & COSTS SUCK!"
