Ratings are a 10-step evaluation of a Database Item by our members (from 0.5 to 5.0 Stars) and display like this on the Search  -

And on the Database Item Show page  -

You can sort any of your Database Item Searches or Subject pages by highest or lowest rated  -

Any Member can rate items (memberships are free, register here) and it is super simple   -

We suggest that you use 3.5 for your base of a good item so that you have room for extraordinary items (i.e. not rate all items from your favorite brand as a 5.0).
