Is there a invention reviewers site?

[Leslie]

Like for restaurants and hotels, there is TripAdvisor and Yelp. Those do a pretty decent job at giving you true reviews (Yes I am aware of some of the controverseys, if you want to bring that up), but I am wondering if there is a popular/central where consumers have purchased products, and reviewed wether they are good or bad, or given a 1-5 star system.

Another option I would be looking for, or if there is such a site is, possible 'One Year Later' Reviews. Many products start off very good, but after a couple of months they end up weakened, of in the garbage heap.

Is there any such sites, or what are the most popular ones?

More of an answer to your title than the actual question, one service that provides unbiased paid evaluations of new invention ideas:

The site Quirky.com "crowd sourcing product inception" evaluates and develops invention ideas with the participation of members, a few have made big money from their ideas.

Your question seems to be more about a product reviews that somehow track back to their inception? A great number of products fail in initial market testing, never really getting any broad exposure.
