Do you know how I can tell when I have an incoming call or message? My phone, which is in my pocket, makes a noise and vibrates. Why the absolute hell would I want my vacuum cleaner to notify me of a call?
And the washer too? Do they seriously think people just sit around at home taking calls every 5 minutes that they need every appliance to be able to make/take phonecalls?
Minimum 2 locks. And the lock featured in the article wouldn't cut it. Or rather it would be cut... and quite easily too.
Possibly even 3 locks if you have a very valuable e-bike. But honestly I would just get a beat up junker bike and ride that instead if you need to park it in iffy places.
