9. Does it have many negative reviews online? 
It's always good to perform an online search for the product's name along with the word "review" to see what comes up. There are a number of sites dedicated to reviewing products in infomercials. Look up your product and see what people like you are saying about it—preferably on a website that is not affiliated with the product (such as amazon.com). Every product will have a few negative reviews, but if you see nothing but bad comments about it, you're probably better off without it.
