Hello
I think it's a good idea. But maybe a second score would be better? Or maybe a medal / seal?
Gold does not use adhesive, silver uses adhesive in few components and bronze if it uses too much adhesive or in difficult areas for repair.
This does not modify the current scale (0/10) and adds an easy to identify mark before viewing the open device.
I would look for a gold computer (without adhesive and easy to repair) but I would not mind buying a smart bracelet or wireless headphones of silver or bronze level, since it is not an article that can last many years.
Good weekend
