Well let’s compare the specs.
Price:
Cool Wallet S- $189
FuzeW - $149 (If you reserve a copy you get it for $74.50)
I think the prices for these cards are a bit high compared to the USB wallets, though Trezor is around 149 EURO. That being said at $74.50 , that’s a really hard price to beat IMO.
Design: Coolwallet S – It is a bit thinner than the FuzeW judging from the pics alone. I don’t see any videos of the FuzeW but the images make it look slightly thicker and more durable than the CW S. The CW S is viewable in ‘portrait’ view while the FuzeW appears to be usable via ‘landscape’ view. It says FuzeW has an IP68 waterproof rating on the site which is nice. I wonder how it is compared to the CW S waterproof.
Battery: CW S has a 15 mAh and the FuzeW has a 13 mAh. I don't know how many minutes/hours the 2mAh translates too with current info.
Support: CW S currently supports BTC, ETH, LTC, XRP, BCH and ERC20. The fuzeW seems to only support BTC and ETH and FXT (which I believe is their altcoin). They say they will offer future support for QTUM and XRP.
Security: Both are CC EAL5+ and have OTP function.
Honestly its hard to tell anything about the FuzeW at this moment aside from whats on their site. The card was made by BrilliantTS which also made the FuzeX so the credibility seems there. The price offering is cheaper and with the ongoing promotion I think it’s a huge deal. The design also looks to be premium with the added water resistance. I guess we’ll have to wait and see.
