This is basically worthless hardware since monero will be hardforking away from cryptonote. Lol @ these guys desperately trying to push that crap on to others since they probably ordered before the announcement and now have a major case of buyers remorse.
I wouldn't say it's worthless. There are tens of CryptoNight coins out there. Sure, maybe 1/3 will switch to CryptoNightV7 or some other CryptoNote-compatible hashing algorithm, but the rest won't. This might just make bytecoin climb higher on CoinMarketCap than monero as we have already witnessed last year and become the king of CryptoNote once again.
