This has two problems:
1. The prosumers can get detached from the needs of ordinary consumers (see: audiophiles)
2. Some products just don't generate enthusiasts. I recently had to buy a washing machine. All the reviews are sponsored and slightly suspicious crap because nobody cares enough to be the Tom Laundry Tips of the world
And yeah for products like these you really need to search prosumer forums for the specific area in question, Consumer Reports would be useless.
