It doesn't fit back and front. I've been sending sticks back and forth for a month, receiving new ones, making calls, sending new ones, receiving new ones... It's a disaster. I have now sent 6 emails, made 2 calls, gone to the post office etc. My indirect costs costs now exceed the value many times over! I ordered 2x16 GB over a month ago. I have never received anything that even comes close received at my home. Please finally take this incompetent dealer off your list!
