The customer service was great, and everything shipped when they said it would.
I received mine early last week for CAD$300.18 2-day shipped to Blaine. They're fantastic. Crystal clear and a nice long range, and buttons that actually work with gloves on.
If you're after one of these BlueTooth communications systems, this is the best price I could find on the 2-pack.
