### ⭐⭐⭐⭐ Good product, but can be better
*by D***L on November 27, 2024*

I've received the keystone 3 pro and tested it out for a couple of days now. I like the system and its security features, but I don't like that it forgets my passphrase and that its sometimes difficult for my laptop, pc & iPhone to read the QR codes. Regarding the passphrase feature, maybe its an extra security feature to forget it everytime you turn off the device, but coming from a Ledger device its pretty inconvenient. On the Ledger you could just simply have 2 different login codes, one for the non-passphrase account and one for the passphrase account, but with the keystone you need to enter the passphrase everytime you switch off the device. Personally I miss this feature and on a side note I also miss having the option to have longer login codes. Regarding reading the QR codes, it goes flawlessly from the camera on the keystone, but on the iPhone, Laptop & PC it sometimes feels the keystone's screen is barely big enough to get a propper read, even in zoomed in mode. Having a slightly bigger screen on the keystone to allow a slightly more zoomed out QR-code I think would have been better. In the beginning I struggled connecting my Metamask and Eternl accounts properly with my Ledger seed phrase, but noticed after a while you need to turn on the Ledger Live option on the Keystone device to get the correct account connected. Sometimes this option resets, so every time I scan QR codes I need to double check the Ledger option is selected, which is a little annoying. Although the above sounds negative, I'm happy with the product as everything else works as expected and full fills my need for a more user friendly hardware wallet compared to my Ledger Nano S (Plus). For everyone considering this product and wonders if an SD card is required: it is optional as far as I can tell. I've updated my firmware purely with USB cable and didn't need any SD card, I've also used the Keystone without SD card. ofcourse updating through SD card may be a bit safer, but I think there's bigger risks in life.
