## Questions & Answers

**Q: Is this MK1 or 2?**
A: This is an MK1. The buttons are awful. It goes from not being responsive at all to phantom key presses. Best used with a reliable power source like a battery pack, though I still would get the newer MK2 or MK3 over this one.

## Customer Reviews

### ⭐ Careful about the model you get
*by B***E on April 19, 2020*

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
*by S***S on July 5, 2019*

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.
*by W***I on January 22, 2021*

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.
