Review on SanDisk (Five Pack) 256GB SD Extreme Pro Memory Card Works With Digital DSLR Camera 4K V30 UHS-I (SDSDXXY-256G-GN4IN) Bundle With (1) Everything But Stromboli (TM) Combo Reader by Christopher Millet

PRO: Tested on nearly 86.5/91.3 MB cards with a USB 3 card reader. Pretty good. Con: Card Reader is a joke totaling 28/21.8 MB. There must be a USB 1 or USB 2 memory card reader that also gives you a faster write speed than a read speed. this is not normal and is a wake up call for me. I don't trust him or the seller to include it with a bunch of fast cards. I will never buy from this seller again.
