Excellent value for money. Very fast on Sony for anyone who doesn't want to invest in CFexpress. So far, reliable.

I am not satisfied. After 5-6 times of working perfectly, it started to have problems during recording. Specifically, while the first few times it recorded videos lasting over 2 hours on a camera without any recording time limit (Canon EOS R7, 128GB card capacity), it then started to stop at 17 minutes, 25 minutes, etc., until I lost my trust in it and stopped using it for videos. The customer service told me that there is absolutely no problem with it. Okay guys, thank you.
Note that my other 2 cards (of a different brand) record 2 hours and 20 minutes - on the same camera, with the exact same specifications, 4k fine 25fps - without any problem.
