Did you read the reviews? "I can’t activate this phone in USA". And it's not the official store, usually it's a third party selling it. I'm not making this up, you can't use them.
You can buy and use a Huawei phone, but it will not have access to Google services (unless you root it? Idk). Other Chinese phone manufacturers are fine though lol
You can definitely use one lol. They have phones for sale on Amazon, on their official Amazon store page.
