Re: Never buy IoT kit
how is the average consumer supposed to tell if a piece of kit requires an external network to operate?
Any packaging for the device should contain a notice of some sort, usually listed amongst the requirements, e.g.:
Windows 10
...
Internet access.
...
If you see a device has that "Internet access" requirement, either don't buy it or do more research into the device.
Also, ask the retailer it is being purchased from, this is one of the only good reasons to buy from bricks and mortar these days, so you can ask in-store any such questions, and if the answers turn out to be wrong, you can return it to the retailer for a refund.
