I bought my first OTG cable from MicroCenter through the salesman. I explained to him what i needed it for and he recommended the cable i bought. It turned out that it was only good for connections to my Old Nexsus 7-2013, not my Nokia G 300 or my external hd.. It turned out I needed a OTG-C cable. Now i have been searching the web and see crazy prices from a $2.47 excluding tax and free shipping to $35 dollars. I just want a simple cable that would connect to my Nokia and eventually my external hd and of course my desktop. The low price i found was on Ebay and the feedback from these sellers were excellent, and the prices tempting. Probably, the tax for it would bring it up to around the $5 range, more than the selling price. I have bought products from Ebay in the past and have had no problems. How can i be sure, not merely looking at a picture if it would work with my devices?
