The following information only applies to the Uni v2.
A backplate is an additional feature you can buy at stenokeyboards.com
Here are some pros and cons of getting a backplate:
- It covers the sharp points on the back.
- Therefore more portable
- More expensive
- Slightly bulkier
- Keyboard is a little louder
- Increased height
I like the sound of no backplate better, but I also like the safety and aesthetics of the backplate.
It isn't necessary, but it is cool to have one.
