It seems that Massdrop is not much different than the notorious other super discount "bait and switch" operations on the web.
From my experience, these kind of online retailers only understand one language, the credit card charge-back fees and penalties. That is the only way to get them back in line and to care about their current and future potential customers.
cdataThe issue in question has been resolved in a satisfactory manner. I'm not sure if it was the supplier/vendor or massdrop's fault but the wrong (inferior kit) was sent.
