It does work, but it only redirects after the whole page loads first then it redirects which means it can take several seconds before it's redirected.

Works well and only redirects to smile.amazon.com when one is logged in. This avoids issues with infinite redirects that amazon can have if one is not logged in and attempts to auto redirect to smile.amazon.com. This is definitely the best version of an amazon smile redirector that I have tried.

Works as advertised, but waits until the full page loads on "www.amazon.com" before redirecting to "smile.amazon.com", resulting in longer wait times. Would be better if it intercepted the request and redirected before loading the page.

I've used many smile redirectors and so far this one has been the least buggy by far, as in zero problems. I know there's a million factors that affect extensions and I have not been paying attention many of them this is a solid extension in my book.
