I got a bluetooth Majestouch sometime a decade or so ago and it's been a daily driver ever since. At the time, there weren't a lot of bluetooth mechanical keyboards out there. The bluetooth bit can be a little bit picky or slow when connecting. It's not as quick and reliable as a Logitech wireless keyboard with a proprietary protocol and dongle. However, the keyboard itself is like nothing Logitech makes. If you know, you know.
I'd absolutely buy another one of these right now if it were showing even the slightest signs of wear, but it's not. Bulletproof. The only keyboard I still use that's older is a Model M.
Filco really put quality first. It's a shame to see them go.
