ColdCard Mk4 is now available for purchase directly, without reservations and extra waiting time.
Price is around $158 plus shipping, but I think you can get free shipping if you spend $499 or more in Coinkite shop.
There is %5 discount with promo code CKBTC, and it would be interesting to see some independent reviews for this new mk4 Coldcard.
I think there are better hardware wallets than Coldcard Mk4 in market today for this price, but others like ledger or safepal are worse and inferior in my opinion.
