Maybe it's because the same thing was already being sold on Amazon as early as February, 2016 according to customer comments? (link was shared by /u/ClintonHardy)
EDIT: read through some of the comments on the kickstarter page, and someone recently said this company sold & ran, and the company buying them out have it for sale on Amazon. I just want to update to say this is a chicken/egg situation (I don't know which came first)
