I'm not sure it's possible to even give a reliability score for a new product.

The only way to do this would be to give reviewers the product a year before it's released. That's obviously not possible in the modern JIT product market economy

The reason I only buy old stuff and basically never a new product (unless it's a early adopter type thing) is so that I can get the community reliability score.

Never pay to be a new product tester
