Summary: I recently Purchased 2 Viewsonic 10pi tablets with 64 GB built in memory. I purchased these two 64 GB Memory chips to augment the memory but found the tablet couldn't read the new chips. I was using 32 GB memory chips in my Digital HD camera and tried the new 64 GB chips which worked fine. I swapped the chips and am happy with the results. at a very reasoanble price.
Summary: Lightning fast data transfer. I didn't test the waterproof function, although I installed it in an ADDIXXION WEBCAM by JVC (submersible webcam) and did not subject it to water. FLAWLESS performance, HUGE data capacity, and reliable SanDisk quality. HIGHLY RECOMMENDED!!!
Summary: Just returned from Safari for 10 days. No problem at all with Canon 70D using video and stills. As it is 64GB i couldn't back it up in my Digimate 111 hard drive, which worked with a 16gb card.It didn't need the back up as all was fine and quick to transfer images to the computer.
Summary: A very reliable memory card of superb quality, easily keeping up with the action. A must have for the latest Full Frame DSLR's! You never have to wait for the camera to be ready for the next burst...
