### ⭐⭐⭐⭐⭐ Truly a bleessing.
*by A***R on July 23, 2025*

Truly a time saver and security greatly improved.

### ⭐⭐⭐⭐⭐ Read instructions carfully
*by J***. on July 4, 2025*

Tricky to set up but if you do it step by step works fine

### ⭐ Not Windows Hello compatible
*by J***X on June 29, 2021*

I recently purchased 2 of theses and was disappointed to find out that it is not Windows Hello compatible and even more surprised when I did a little more researched and found a device that was not only compatible but cheaper. I am not blaming anyone for my purchase, I should have done more research before I made the purchase and I know better but you would think all companies that sell tech would be compatible with Windows. So my question is when can I expect a firmware update to bring this product into the 21st century? My score reflects the lack of compatibility with one of the most used applications in the world.
