Nice cool wallet for storing crypto

Cool design, does what it’s supposed to. Works very well with the app. Easy to understand. The only downside is not all crypto is supported (monero) for that you might want to look into getting a ledger device

A very good product but no support for BSC I thought it had this.

The wallet is very easy to setup and i love the way it works with numbers vs letters.Over all I am going to spend even more and get 2 PRO's because i want BCS and M-Sig

The future of hardware wallets!

Excellent experience with the CoolWallet S. The biggest main part for me is with the new update. It allows you to display the seeds on the device itself instead of on the phone. The credit card size is perfect for on the go. The E-paper screen is trip to look at for a device this small. No more lugging around cables, signing is done wirelessly. The app is good but I would like it to be a little more streamlined. It does what it needs to do and does it easily. If I had to find something to nitpick about it would be the display. Higher resolution epaper screen would be helpful in reading and confirming sent addresses more easily. Other than that, currently it is doable and not worth docking a star. With experience with Ledger Nano S, and the original and new Trezor Model T, I Highly recommended and welcome the Coolwallet to my arsenal of hard wallets.

Comes with only one charging cable

I didn't know this duo pack comes with only one charging cable. It would be helpful if the seller mentions this as this is important information for first timer purchase like myself.

Credit card sized crypto hard wallet.

Very cool. App works well. Credit card sized. Just needs more cryptos added.

🥶Cold storage🥶

I like many others have digital assets and the absolute best way to start to store your digital assets is off line, and in cold storage . coolwallet has there finger on the pulse of the future with an NFC chip in it and a Bluetooth waterproof tamper proof e-paper reader screen 📺 that can fit in your wallet updates to the app and expansion of assets support and there customers support was spot on 🤓 this product is ready for prime time.

Basically worthless

Clear scams in the included app but technically that's a matter of opinion. But literally as CoffeeZilla is posting videos about a token and its collapse collapse, they're working to support and promote that same predatory lending... Like guys, I just wanted to store my crypto. But make no mistake, if this was a hardware wallet then effectively the software is adware that tries to trick you into poor financial decisions. One star for this and all crypto hardware products that blur lines by acting as a custody product then promoting lending for their own gain.

One faulty card

One of The cards hard the little charging metal point fall out day one... not happy about that, so i haven’t used it, going to try and super glue it back in and test charging capability after i attempt to fix it. The other card works and pairs well
