If someone could give us some advance about this CFexpress type B card?

Recently, I got a card brand name is Renice! Is there any specialist who could give us some advance on those cards?
The samples would be borrowed for testing purpose.

RAW VIDEO support 4K 6K
Operation temperature -10°C - + 70°C

if anyone could give me some feedback that would be great!

Do they claim to support the VPG400 specification? A lot of CFe cards will be fast until their cache runs out and then drop to speeds that make the old CF non-express cards look fast.
The thessdreview.com website tests this by copying a large file to the CFe card and see if the windows copy dialog shows a constant speed all the way. So far all 'cheap' cards without a VPG400 rating perform poorly on that test.

Also, the 'CFast 2.0' in the description is a red flag.

That is the geekiest of sites. The good news for me on it is that it reviewed the Manfrotto 128 CFEexpress card I bought as an el cheapo and I have never seen reviewed elsewhere: "Our testing of the Manfrotto Professional 128GB CFExpress Card was a complete surprise to say the least. When speaking of CFExpress Cards, we envision a triangle comprised of sustained write performance, low temperatures and data transfer speeds. The Manfrotto Professional literally blew all but the Lexar Diamond away with sustained write performance at 1.44GB/s while maintaining a low temperature of 57°C."

Congrats on finding such a good price/performance deal!
