I think this is probably a good thing as Vodafone have never really been committed to it, and they need to focus on their bread and butter.
I bought one back in October 2019 but only used it for a few months as it felt like a science experiment that wasn't ready for mainstream consumers. Given the limited amount of use I got out of it I would like to get a refund, but I'm guessing they won't offer that to anyone who purchased their units more than a couple of years ago.
