Originally I was sent the wrong cable - M/F sent rather than M/M - when I called - I had absolutely no problem getting through with the customer service staff who quickly processed sending me the correct unit (after a verification picture was sent). The item was received in about 5 days. I have tested the item and will likely order more next time I place on order on this website. I have never had a problem with items that I have ordered from this site. customer service has been very responsive in my experience The correct item works perfectly.
