This is a great idea!
Covering some of the most common issues with items that are difficult/impossible to repair sounds like a good approach.
Some ideas for products:
- For impossible to open, how about Apple Airpods (more info). Some toasters and blenders are pretty tricky too.
- For short-lived security patches / software updates, certain types of Android phone (I think Huawei have a pretty bad record on this, but perhaps someone else can confirm this)
- For issues with quality control, a Nintendo Switch could be eye-catching (and a chance to mention the “JoyCon Drift” issue). Alternatively/additionally, a MacBook with a last-generation butterfly keyboard (for this issue) could work too. As a bonus, both of these are also good examples of manufacturers trying to make repair harder by using unusual/proprietary screws (tri-point for Nintendo and pentalobe for Apple)
- Much of Amazon’s own brand tech isn’t made to last or be repaired. An Amazon Fire Tablet is a great example of that.
iFixit also rates the repairability of various smartphones, tablets and laptops. It might be worth looking at some of the lowest scoring devices there!
