These work great with Samsung S3 and Note 10.1. Ipads and Iphones got nothing on this, those users are amazed when they see all the parts manuals and technical documents and pictures I have at my fingertips (I have over 30gb of documentation and pdfs and pictures), all without some &#34;cloud&#34; that sucks your data especially when traveling out of the country, and with 32gb device memory still more than half free.
