People who got a counterfeit from this listing, which vendor?

Counterfeits are possible with all 3rd party sellers, as well as Amazon direct when they mix inventory. Always test the performance, capacity, and consistency of each SD card you purchase. Counterfeits can have inaccurate visuals, while some can look entirely genuine, but what they can't fake, is the performance, especially write throughput over an extended period of time, as the goal of a counterfeit, is to sell low quality and in some cases, lower capacity NAND at high end NAND prices. The easiest way to spot counterfeit NAND, is to do 100% linear write across the entire card. It will not only help to verify the advertised capacity, but it will reveal counterfeit tricks such as using cheap QLC NAND and having the first few GB function in a pseudo SLC mode so that the card will look good on crystal disk mark while being extremely slow when you write more than a few GB to the card.

Does this work with go pro hero 7? thanks.

Yes of course usually anything with v30(video speed class) is great for video which is 30mb a sec the go pro 9 does like 5 to 8 Mb/s with 4k 30. Also with file transferring like a switch. A3 being even better. 5k If you plan on doing that a lot a lot. You might wanna look at a 60 class.

Is this a Geniune sandisk?

I am using with my GoPro 7. So far it's working perfectly. Everything indicates that it is genuine.

Waterproof, shock and vibration proof, protected from airport x-rays, temperature proof

This latest version of the top-of-the-line Extreme Pro line is labeled both with V30 for 4K video recording and A2 rating for app speed. It’s rated for 90 MB/s sequential write speed and 170 MB/s sequential read. SanDisk comes out with new models quite frequently, and there’s not always a lot of performance improvement between them (which is why there are so many near the top of the table below). This latest version claims a boosted read speed over the previous model, but the reality is that the past few iterations of the Extreme Pro have had much the same write speed, so if you can’t find this latest version, you can be confident getting a recent previous version.
