I try many tools
Jungle scout：the tools are really good to help filter down to some product ideas. Especially their chrome extension,It’s great, but Monthly Sales and Revenue Estimate. I’ve found JS estimates to be way too optimistic.
I’ve checked this many times with my products and friends products.
the same problem with AMZsocut and unicorn amasher.
I found a new software named sellerspirite, compared with my product‘s ’monthly sales and revenue, the maximum difference within 10%, but their chrome extension is not as well as jungle scout, it just has a keyword research function,and without any function of sales and revnue, it’s only working in their website.
This is just some of my experience with product research software.
