Review: Good hardware wallet - This is the newest and best version of the Keystone. Works great. Unlike previous versions, this one has a built-in battery that holds a charge much longer than the old removable batteries of the past. Easily sync to a software wallet on desktop or mobile. This device can also hold multiple wallets with different seed phrases.
Review: DO NOT BUY - desertcart didn’t let my original review post so I’m trying again. DO NOT buy this product for the following reasons: 1. I experienced an error trying to sign a transaction (send money) almost immediately. Can you believe Keystone support asked me to upload a video, seriously, a VIDEO!!!, of the QR code presented during the transaction that failed. Are you kidding me??? That’s absolute insanity; ignoring security and privacy which is the ENTIRE POINT OF HW WALLETS, especially air-gapped HW wallets. From this support request I realized their Support resources have NO CLUE as to the functionality of their products/devices. Their support doesn’t even address the basic concepts of the device you want to purchase TO PROTECT YOUR FUNDS. No secure support (they asked me to upload a video of the QR code via telegram and then via email! Email??) It’s hard to even conceptualize their idiocracy!!! Telegram and emails are not secure and possibly the WORST support options available. (And you want to trust the protection of your your funds with this company???b) I asked for secure upload link multiple times and they just ignore my request. Is this company working out of a garage? 2. It’s been almost 3 months and Keystone continues to ignore my support requests. 3. Keystone is willing to refund my money, but still ignores the problem with their defective device 4. No regular battery cover included with Pro 3. We all know rechargeable batteries only last so long. The previous version included a back cover that allowed you to use regular alkaline batteries. This is paramount for the longevity of the device. I mean, what happens when someone dumps a dozen BTC on this device and doesn’t touch it for 10 years? The rechargeable will battery fail and the device will not work. 5. Don’t use Shamir secret keys. Keystone and Trezor HW wallets support Shmir’s Secret Keys. If you use a SSK with Keystone you’re 100% reliant on Trezor (which is a great company) because Keystone and Trezor, at this time, appear to be the only companies that support SSK. 6. This mistake can be permanent if you set your consensus layer fee recipient address to an address whose private keys are protected by this device. Only option is to exit your validators and restart with a new wallet address and I think KEYSTONE SHOULD PAY FOR THIS SINCE THEIR DEVICE IS DEFECTIVE!!! 7. I’m going to seek reparations from Keystone due to these problems and will seek legal counsel considering the their negligence. DO NOT BUY THIS PRODUCT. JOIN ME IN A CLAS ACTION LAW SUIT!!!

Where do I start? The ease of finally being able to get my Keystone 3 Pro in 2 days was wonderful! Can’t say enough about the Keystone. Setup was an absolute breeze. Love the fact that it’s 100% air-gapped and not accessible via WiFi. When they say “COLD storage” it truly fits the definition 100% Highly PLEASED ⭐️⭐️⭐️⭐️⭐️
