I bought them less than 3 months ago and one of them has already stopped working. It is advertised as 20 for writing and 70 for reading but these only increase to 13 and 20 respectively. I have used them on my Wyze Cams V2 and Revain Fire Tab 10 9th Gen. The tabs said they were slow to respond to SD when I formatted them to increase storage capacity (I used this format as I don't use them to transfer files between devices). The one that stopped working was in a V2 camera for which I had to reinstall the base firmware as it got corrupted when the SD stopped working. I asked if it was High Endurance and someone said yes, which I really doubt based on the slow response on both of my tabs and an issue with one of my cameras.
