Careful about the model you get
The model sold by the seller was the MK1 model, which is old and has design flaws. Make sure you are buying the MK2 to MK3 and you are better off buying direct from Coinkite direct.

The best option on the market
The one area that I can recommend with this is to use a cell phone battery pack to power this, that ensures that the device never touches anything on the internet (and it makes the buttons work better). Otherwise great product with good support.

Arrived inoperable.
The item arrived with no visible damage. When trying to enter a PIN the key pad would ether not respond at all or would enter uncommanded digits. Item is inoperable.

DO NOT BUY ON AMAZON
Only purchase the Cold card wallet from the official manufacturer through its official website (coinkite.com) to avoid potential theft. Buying from third parties (especially imposters) risks your assets.

Bitcoin #OPSEC 101: only ever buy hardware direct from the manufacturer (@coinkite in this case)
If you don't buy direct from the manufacturer you introduce one or more completely unknown attack vectors - you would have to be nuts to do it at any cost savings level - it puts all funds you ever store on the device at risk!

Don't buy Fake COLDCARD.
Becareful! Don't buy Coldcard from Amazon. You don't want to lose your valuable bitcoin for buying fake coldcard. Go str8 to the source (coinkite).

Impossible unless you are a techno geek or a programmer.
I just wasted $200 bucks. I'll never be able to make this thing work. Extraordinarily complex.
