Today the battery of my Blinkytape had a sudden encounter with the floor and the USB connection did not work anymore. The tape itself and the USB cable were not harmed, and the “Power” logo lit up normally. So I took my ifixit tools and start the teardown.
I would give it a repairability of 5/5. I only have had to resolder the USB connections and put the whole thing together again. Works like a charm.
