KEYSTONECryptocurrency Hardware Wallet Air-gapped, 4-inch Touch Screen, Store Your Crypto Securely (Keystone 3 Pro)

I recently purchased the Keystone 3 Pro, and it truly exceeds expectations! This device is not only sleek in design but also packed with advanced features such as open-source software and a user-friendly touchscreen. Setup was a breeze, thanks to its intuitive interface. For anyone in need of a secure, air-gapped, and anti-tamper cold storage wallet, I highly recommend the Keystone 3 Pro!

Amazon 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 device4. 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 ⭐️⭐️⭐️⭐️⭐️

The media could not be loaded. As an 18-year-old investor, I have found that the Keystone crypto wallet is an excellent choice for managing digital assets like Bitcoin and other cryptocurrencies. While the quick battery drain is a drawback, the overall quality and ease of use make it a worthwhile investment. I am eagerly anticipating future hardware releases from Keystone, as they have the potential to rival established industry leaders such as Ledger and Trezor. If they were to introduce a more compact, pocket-sized version with Bluetooth functionality, it could quickly become a top contender in the market. The inclusion of a camera and QR code scanning feature in the Keystone wallet sets it apart from other options, offering convenience for managing a variety of digital currencies. However, the fingerprint scanner's placement on the back of the device and its slow, finicky performance have been major drawbacks. In comparison, the thumbprint scanner on a 2-year-old Motorola G Power phone works seamlessly and is located on the side for easy access. The camera on the Keystone wallet excels at scanning QR codes but unfortunately lacks compatibility with other wallets or chains, which can be limiting. Ultimately, while the software and integrations of the Keystone wallet are impressive, the subpar hardware performance led to the decision to return the product.

Love the big screen!!!!! Easy to set up, works good so far.PS: the screen protector has so many scratches that you have to peel it off to use it

Needed a hardware wallet that is open source as opposed to ledger which I also own. It works well but the biggest issue is the erratic battery as others have mentioned. Works well with suiet wallet for Sui; solflare for solana and sparrow wallet for BTC on desktop only(MacBook). I love the passprhase support for extra security.The battery drains out of nowhere and it dies. I initially thought it became bricked.The supplier of the battery is substandard, I hope keystone fixes this. Will not buy again until newer model.

Bottom Line: If you’re tired of hardware wallets with small screens and physical buttons, the Keystone 3 Pro is a great alternative. Plus, it integrates with MetaMask giving you easy access to DeFi.

Best security in the industry but one of the wallets won't charge and they've been avoiding allowing me to return it with ineffective suggestions. Really kinda annoying. I just want to return for another wallet.
