Haven’t used it to much, but I heard good things about it. I’ll definitely use it more once I get my Apex Flex implanted.
I seen also that Digital Logic released the JustID, which is a “NFC UID Reader Keyboard Emulator USB Dongle”, just like the KBR1. I might try it out. They offer different versions, one which seems might read the xSLX.
The JustID might help folks who are looking for a smaller KBR1, or looking to embed it somewhere…
