Incredibly handy add-on! Helps me find the 'tried and tested' products on Amazon with ease. Gives me the peace of mind knowing that I ordered reliable products for my family without having to manually search for hours through each individual listing. The installation was easy. It is a cinch to use. A little blue button pops up right next to the Amazon sorting options and voilà. You do have to click the department link on the Amazon search side bar for the sort to work best. Saves me a lot of time/headache and totally worth the 5 bucks a year. Thanks for creating this app. Hope this review was helpful to someone :)
