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: I am a photographer and since we shoot a large amount of pictures on a wedding day, and usually there is no time to sit back and download them, I needed a large card. I have always used SanDisk cards before and have no problems with them at all that was the other reason I picked this Brand. The cream of the cake that I got a free recovery software as well from Sandisk just in case something bad happens.
