Review on 📦 Wholesale Lot: 5 Pack SanDisk Ultra 16GB SD SDHC Memory Flash Card - High-Speed Class 10 - Read Speed up to 48MB/s - Bulk Purchase with 5 Cases by Ryan Garrison

Bought these charts for a rough river trip, wanted more than enough capacity for 7 days, tested all 5 charts before leaving. Cards 1-4 went great, but #5 got stuck in the receiver and refused to be ejected. I had to take it to a garage to pick it up. Not satisfied with the repair bill. The 5th card looked the same as the other 4 cards, if I took it down the river I would have been unlucky.
