I think there are a lot of things that are behind subscriptions that you do not realize. One example is computer mice. They use switches that are only rated for a certain number of clicks before they stop working. I was going through mice about once every 18 months. I decided to learn to soldier and just replace the switches once they broke. I found that the switched in the $100 Logitech mouse I bought were only rated for 5 or 10 million clicks. The switch they use can be purchased in a 70 million version. Why didn’t they use that from the start? I ended up repairing 3 mice and have a lot of extra switches sitting in a bit at home.
