I bought AA wireless for this; I think it was the original product.

Review sites are just as bad, they get a product for free, give it a stellar review after 1 day of playing with it, and move on to create the next SEO spam article.
If AA Wireless is really good, maybe someone has a recommendation for the "other garden".
