I bought my 02ring in Sept 2021 but lasted less than 2 yrs
I bought my 02ring in Sept 2021. In May 2023 it started giving wildly variable readings. I have tried factory reset and a firmware update but now (August) it freezes on start and often seems to switch on randomly. On Facebook Wellue have repeatedly tried to limit their liability to one year using their warranty unreasonably. Under UK Statute it should be of satisfactory quality for a reasonable time.
