We bought a Vivofit Jnr 2 Star Wars edition band for our son for Christmas. The first band wouldn't start up at all so had to exchange it at Argos where we bought it.
The second one lasted about three weeks before the time display froze at 18:26 last night and flashed on and off continuously. Then the alarm began beeping an hour later and there was nothing we could do to turn it off. Even the 10 second reset failed. Eventually i found a watchmaker's toolkit and removed the battery to give it a hardware reset. When replaced, the display showed a rather attractive barcode pattern for an hour before eventually going blank. I'm concerned about the likelihood of getting a third dodgy band from a duff batch if i take it back to Argos, is there anything else I can try?
