tool4seller - Amazon Product Research

This is an amazing service I use it a lot and it helps me a lot in many areas and it's free.

Tool4seller is an useful extension for product research. The accurate data, prodift margin calculator and insightful analytics work well for every seller. And I love its customer service team which always gives me the fast response. I will highly recommend this tool to any Amazon seller.

This tool is very useful for me. With it, I better understand the market, my competitors and select the right products to sell. It helps me operate well in my business!

It can help me analyze competitor products from various dimensions and help me filter many useful keywords.

Loved it esp the review insights. Kinda a good way to know what customers care about and then improved my listings XD havent tried all features but so far so good!
