Wafer USB Bussiness Card Flash Drive Blank DIY Memory Stick Wholesale Bulk Pack 10 (16GB, White)

Whenever one of my books needs additional material such as video or web links, I add one of these by hand after getting the printed books back from the publisher. They lay flat and hold a ton of info, making the book easy to stack, store and mail.

Overall an excellent product. However, the USB plug does need to be modified to fit the standard socket. All it takes is a quick swipe with a razor blade on one edge of the plug. Thanks, I will order more.

Of 10 (ten) items promptly delivered ("Wafer USB Business Card Flash Drive Blank DIY Memory Stick Wholesale Bulk Pack 10, White"), 4 (four) could not be recognized/formatted by MS-Windows 10 Professional. There was no problem with fit of the hinged card connector arm into the computer USB port, just failure of the operating system to recognize the inserted device as a USB drive. The other 6 (six) formatted without any problem to the full 1 GB capacity; no indication at all that the cards are fraudulently claiming more capacity than they actually deliver. Best guess: KLD Electronics INT'L Co., Ltd fabrication process results in some cards with bad memory blocks, which the manufacturing plant's quality control department cannot afford to screen out so that these items are not shipped to customers. For those who don't care to purchase at an economy price and sort through the delivered items to weed out the defective units, it's probably wiser to select a seller of this product type whose Amazon customer reviews are overwhelmingly positive.

Cards feel as though they are well made. Transfer speed is great. No errors or format problems.

Worked great, got them fast and the CS department was on the case. Ordered before Christmas and Amazon stated it would arrive after Christmas, so I canceled order. Received message from CS dept @ KLD the next day with a tracking # stating that it would be there before Christmas. It was. Nice job KLD. Pleasant surprise.

Keep it in Ur wallet like a credit card. There when u need it.I wish they had the 3.0 version for transferring large photo files.

The insert tab is too wide and cuts little grooves in the device you're connecting to. Some just don't work, they just won't mount as a drive. So great idea, poor execution.

Good Product
