The Perfect Product? [HELP]

I hear different things left, right and center. See what competitors post, whats already selling, what no one is selling, market research this, market research that, go to this website, do this, do that.

Is there anyone on this forum that provide a little bit of guidance when trying to find that 'Golden' product?

I know that there is a ChromeExtension which allow to see how many sells and from which country the product get on aliexpress for the last period but I don't remember his name...

So if you find it, you can monitor some products to see if people already sell them and try to get your part of it...
