if i buy a device from a startup, why should they be exempt from providing service manuals, batteries, etc, if they haven’t, say, made enough profit from the device first? frankly, it’s the smaller players who are more likely to go under, like Vanmoof, where as the consumer i’m MORE in need of the right to repair it myself. I’ve run into this personally with a Rapsodo golf launch monitor with a faulty battery, where i attempted to replace it myself. I couldn’t find the battery online and the company refused to sell me just the battery. They said i had to buy a new device.
