You need to review them yourself to know which one will bring money to you. As far as I know, financial products have higher refund rate than other products. So I would recommend other products to your products, but not financial products. Good luck mate.
i tried financial products when i started and it was disaster. Try other products, try searching by their gravity and then see if you like the products or not. I would recommend something with gravity between 50 and 100. Good luck
