Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the quality and compatibility of the flash drive. For example, they mention it's reliable and works perfectly over USB and NFC connections. That said, opinions are mixed on performance, value, ease of use, security, and the key.

There was a problem filtering reviews right now. Please try again later.
While I was originally uncertain about the durability of this key, it's lasted me over 3 years now with HEAVY use, and I even bought a second one recently and registered it everywhere to make sure I have a backup. The contacts have corroded slightly over the years, and the plastic has been worn out, but it's somehow survived this long despite being on my keyring with all my other keys scratching it, and while working as a laborer with them always in my pocket.
On a second note, I believe that this only used to work in Chrome (Chromium works as well if you still use a 32 bit install or an old OS, but I can't vouch for whether or not it would be able to recognize the device if your computer is that old), but it now also works on Firefox (and TOR by extension, since it uses Firefox).
This key does NOT work with Windows Hello, but as far as I can tell, neither do Yubico products or any other hardware keys without Azure AD Premium (though I can't even attest to that working properly), so this is the fault of Microsoft, NOT Feitian. Windows Hello has "hardware key" as an authentication method, but rejects any of the keys I've used, so I don't understand what it wants you to use (I've seen reviews on every Yubico product with the same information). Yes, Yubico has software to change the login to enforce hardware key authentication (which doesn't work with Feitian), but this can easily be bypassed by booting into safe mode, so for the security conscious, I'd simply recommend ditching Windows, or just dealing with a password without 2FA. I believe that the same is true for Rohos, but Rohos works with Feitian (I've confirmed this). The only downside is that Rohos costs $32USD after the 15 day free trial, and with a security flaw that big, I don't believe it to be worth the money. I also have not been able to get it to work with my Microsoft account, but I again suspect that this would be the same for a Yubikey, as the same dialogue popped up when it denied the key. I hope that this changes in the future, but given Microsoft's turnaround time on features and the continuous lack of certain security features, I don't know when or even if that will happen.
I've seen some people address security flaws, but Feitian has since fixed them, and been very responsive to feedback given by customers! The original flaw with UF2+CCID mode being exploited is gone now, and they improved their packaging to a tamper-proof plastic and cardboard package.
For the price, this is absolutely the 2FA device to get, and unless you care about storing PGP keys, then there's no reason to buy a Yubikey over this device.
Another side note, Feitian is the company that makes the Google TITAN series of hardware keys, and they're simple rebrands in white, so I recommend you buy them straight through Feitian instead of Google, simply because of markups and such. If you care enough about the color, then I suppose you can get the Google TITAN keys, but I honestly prefer the black one Feitian sells anyway.
I'd also like to add that yes, Feitian is based in China, and these keys are manufactured in China. They still use FIDO2 and other international standards however, so this fact does not matter for security reasons. There is no way for them to see what accounts are used with this device, so even if they DID store and track these devices, they couldn't use them for anything. When you understand how these devices work, it doesn't matter from a security perspective who manufactured them, and given the responsiveness to a previous security threat with this device (which was hardly even a vulnerability), they've proven that they certainly care about security. Another one of their products that had a vulnerability in the Bluetooth pairing method (which I don't personally agree is a secure protocol to use in the first place, but that's beside the point, since I believe they were simply trying to appeal to a wider audience) was immediately addressed, and they replaced the product free of charge for every customer who owned one. Feitian actually has a significant history as a security company that I recommend you to look into if you're still questioning their credibility, but with how they've handled their products, and specifically the type of device this is, it doesn't matter that their products are manufactured in China.
TL;DR: As a long time user, I highly recommend this product for it's durability, usability, and compatibility. It achieves the same thing as a Yubikey (except for storing PGP keys, but if you don't know what those are, then it won't matter to you), for half the price. My current key has lasted me over 3 years, and I suspect it will last me far longer still.

My current key has lasted me over 3 years, and I suspect it will last me far longer still.
So far, I haven't found any problem using it with any service I use.
In my experience, I sometimes had to press the "button" multiple times when using this via a USB OTG cable on my tablet. Whether this was due to issues with this unit, my tablet, the OS, my apps, or the OTG cable, I'm not sure. Ditto for holding the key up to my phone for NFC mode. However, in all cases it eventually worked. If sites tell you your browser isn't supported, check online for instructions on how to enable U2F in your browser (in particular, Firefox needs a specific about:config option enabled for some websites).
If you're wondering why U2F is better than other options like codes sent via SMS or generated by authentication apps, the main reason is better security. In addition to being vulnerable in other ways (e.g., stolen TOTP secrets, social engineering of phone carriers, stolen SIM cards), those other methods can't protect you against a well-done phishing attack - a phisher that can trick you into typing your password on a fake site can easily ask you for your SMS/authentication code and use that and the password to access your account. Some sites use mitigations, like adding the IP-based location to the text message or alerting you to new/suspicious logins, but U2F provides a much better defense: if you're on fakebank.com, the U2F key will add that information to the response it produces, and the legitimate bank.com won't accept it.
This unit does also include some other "smart-card" type features, but I found them to be of limited use and not well documented. For example, it's somehow possible to store RSA public/private keypairs on here for use with a computer, but I couldn't get this to do anything useful (using opensc on Linux). Feitian has some tools that let you select a PIN for this functionality and also use it to automatically type some form of one time passwords, but I didn't find this feature necessary/useful and don't use it.
