Excellent, quick service. They sent me a very short amount of shielded circuit wire. It had been difficult to find someone on the Internet that would send me such a small amount.

Excellent online experience. this is the PERFECT wire for my application. This is a very high quality shielded wire, Very small overall diameter even in the larger AWG sizes... The 22 AWG I am using is perfect for my application.
