To be fair, MTBF is not something you can measure in a reasonable time for these kinds of review sites. Far better for this kind of thing is niche-specific youtube channels. But in any case, what you're asking for here is a prediction of your future satisfaction with a product. It's a non-trivial problem even for the most innocuous purchases. Will I like Lysol or Clorox wipes more? Who knows, and the reviews aren't going to beat first-hand experience in any circumstances.
