This hardware wallet is suitable for storing ranges of coins like Litecoins, Ethereum, Bitcoins and much more. It was launched in 2015. I used this wallet for almost three weeks, it had its good sides and the bad parts. This hardware wallet stores private keys offline for the safety of users funds. Thus wallet is flat-like and easy to carry about(its even pocket sized and can fit into an actual wallet). Coins cannot only accessed on this wallet, it can be linked to Android devices with Bluetooth. This wallet is almost different and unique from other wallets coupled with the fact that it is a cold wallet. Using, 2+1 factor authentication, Cool wallet S seeks to further intensify its security features. The wallet is very lightweight and surprisingly waterproof. Connecting to my device using bluetooth was very tedious as the wallet kept disconnecting after connecting for a little while. Frequent verification before every transactions began to piss me off. While I was using the wallet, after a full charge, it didn't last me more than three days as against the original two weeks that was advertised. The downside to this wallet is it's cost, the wallet is very expensive to acquire with shipping cost inclusive( it was almost $116 according to my calculations). They should try to also increase the amount of the standard transaction per day. Cool wallet isn't that cool after all!
