Know your product before You Sell It

Product knowledge is by far the most important crucial component to train when it comes to dealing with your product. Before you sell your product, make sure you know it outside and out, you wouldn't want to be caught without an answer if your prospect had a specific question. Suppose about it, if you were interested in buying a product from someone and they could not answer your simplest of questions about the product, how important faith would you have in it? Presumably none.
