Not a search engine of anything, much less Amazon Rated 1 out of 5 stars

Not sure if this worked or was useful once, but now all it does is take you to http://a9.com/?q=thing+you+searched+for&sourceid=mozilla-search . Save yourself the trouble and just go to that page.

Repeat--Not supposed to be an Amazon.com search engine Rated 5 out of 5 stars

This is an excellent search engine. It is not meant to be an amazon.com search engine, so ignore the reviews that blast it for not doing so.

disappointed, too inconvenient. Rated 1 out of 5 stars

This one is really, really bad. Please give us the old amazon search engine!

Rated 1 out of 5 stars

Just awful! I just want the old Amazon search bar. This engine leads to a noisy page of what can only be described as spam.

Rated 5 out of 5 stars
