Optimum - Your Secure Crypto Hardware Wallet for Bitcoin, Ripple, Ethereum, USDT and Many More | Trusted and Open-Source Cold Storage Crypto Wallet

Works great, let's me store all my crypto in one place that I can stash.

Horrible!!!!! The little paper that come with it has a QR code for setup it doesn’t work… then after surfing the web to find a FIRMWARE I got it to work. But now I can only receive money and not send… then once I got money in Xrp to test it , it tells me I can’t send it out cause I have to keep 20 xrp in account. I see nowhere to cancel And get my money back. PLEASE DONT BUY THIS AND GET SCREWED LIKE ME. You’ve been warned!

Great little wallet. I thought I had a problem as my Shib one day didn't show on it. Since I own over 38 million coins I was concerned as it seemed lost, but the tech support guy, named Max, jumped right on it and discovered a glitch in the blockchain. Within a couple days all my coins showed up perfectly. Hats off to Max in tech support, friendly and smart.

I highly recommend the Prokey hardware wallet to anyone looking for a secure and trustworthy solution for storing crypto. Its combination of high-level security, open-source transparency, user-friendly interface, and great customer support makes it an excellent choice in the hardware wallet market. Five stars from me!

I have been looking for a hardware wallet where the computer or phone memory has none of the private keys ever. This was something I wanted to try and see if it fit for me. This did not work on my linux machine. It kept saying "Connection Error" and ask me to disable a nonexistent experimental webusb setting. It does show up in lsusb list but not sure why the chrome on linux can't see it. I did get a windows laptop to run it but didn't have chrome but it worked in Microsoft Edge. The usb cord that it comes with is really short and the writing on the screen is very small. If using on a desktop, I would suggest finding a longer cable and on windows laptop connect on the side USBs on not the back ones so you can easily see the readings and press the buttons. Other than these problems, the web based wallet seems to work. There does seem to be lots of audits regarding the veracity of how keys are stored and processed in the device. It does seem that it relies on prokey.io website to be operational to use your wallet. I couldn't figure out or find information on how to use the device without that website. Overall, does seem like a legit hardware wallet but as usual does require more research to make sure the device satisfies the needs for storing crypto.
