Amanda was super friendly, helpful and part quality is A+!

My new David Clark headset arrived earlier than expected and everything was perfect. Whole order/delivery experience was excellent.

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!
