both my kids are using my old Filco TKL keyboards with blues. Absolutely no complaints from either of them. Only issues are that the footpads are getting a little worn down, one is missing, and I think I spilled beer on one many years ago before I gave them up.

I also have the Filco keycap puller. Keyboard cleaned and saved!

I now use a Keychron K2 with browns. My fingers are getting too old to use blues on a regular basis.
