Ngrave did not send me a test model, so I had to rely on existing reviews from friends.

According to those reviews I see no reason for the high price setting.

Ngrave did not give me any arguments that prove otherwise.

Ok, it has a Eal 7 chip, but the Eal 5 and 6 also are doing the job.

As I have not been able to test the device myself, I cannot give an opinion on the quality and operation of the software, nor on the quality of the device and the battery.
However, the Ngrave wallet strikes me as very expensive, especially since it comes with an irreplaceable battery.

If the battery fails (an average battery lasts 4 to 5 years), there is nothing else to do than to buy a new "expensive" device, or constantly plug it into a power supply...

However if you want a wallet with the most secure chip on the market and you don't mind about the price, the Ngrave can be your thing.

Pros:

Security.

Good support.

Cons:

Not replaceable battery.

Price.
