You can actually fix the display-glitching yourself by adding a paper/cardboard shim. It actually works! There's an excellent post[0] that outlines the process. I had to redo mine because it wasn't quite thick enough, but after I did that mine was good to go for a long time. I think you might have to redo it when the shim gets worn down and doesn't put enough pressure on the display connector? Not sure...

They did have great potential but apparently consumers didn't agree. And then they sold their IP to Fitbit. :(
