Just what I needed
I've been looking for a solution to at-a-glance information in my household and the TRMNL option was perfect. Simply plug-and-play and super easy to get started. Kudos to the team! I'm already considering a second or third device

Life improved! But flicker is too distracting.
Love the features, long battery life, and colours!
Would be 5-star, but every screen refresh, the whole screen spends ~15 seconds spasming/flickering. The flashing is too distracting/distressing to leave the device in commonly-used areas (dining or living room), so its main purpose is self-defeated.
