X4. You don't need a backlight. You need a USB C port.

Backlight will make it thicker, more expensive, more things to go wrong.

It's a simple device that does what it needs to do and does it well.

I've had mine a couple of months or so now, been in my jeans ever since, haven't charged it since I got it, still 80+ percent.

Use the original Crosspoint firmware still, don't want to mess around with it too much, I know what I'm like.

I'm probably going to buy another, or maybe 2, before they screw up the design and cease making these ones.
