Perhaps I should put : the most convenient hardware wallet. But that will take newbies a little bit more time to understand that it means great security as well.
CoolWallet is worth having because it gives you great convenience and mobility while not losing security. It connects with your smartphone via Bluetooth, giving you ability to make transactions on the go without having to bring a laptop for wallets that work with USB port.
CoolWallet has some interesting features but is priced at $119. You can get a Trezor for $99 or a Ledger Nano S for $65. The CoolWallet devs need to make a case, explain why someone in the market should pay more for a CoolWallet. Also the next gen hardware wallets like Trezor 2 and Ledger Blue will be coming out late this year or first quarter 2017. People who buy hardware wallets tend to buy from companies who have been around a few years with proven products.
Don't get me wrong... I'm not saying that CoolWallet is good or bad. My issue is people that do drive-by posts saying that something is the "best" with no other reasoning or supportive documentation behind it. Then... You click on the link and it's a referral link to the product. I'd like to say "Duff beer is the best" and then put in a referral link to "Duff Beer" but I don't. If someone says something is "the best, most secure, etc" I'd like to know why they think so.
