I went through 3 pebbles with the screen corrupting, and sending it back for a refurb.
I'm jealous that yours is still working, and I'm looking forward to getting back in the fold. My Fitbit Versa that I finally got after the acquisition is definitely spiritually related, but after Google bought Fitbit and got involved it became terrible with bugs.
They did the decent thing with the Versa and refunded everybody.
