Allowing your customers to comment on products you offer for purchase can increase their sales rate. Positive comments left by visitors will help undecided visitors with their purchasing decisions. Unwanted comments and spam, can be a problem, so you will want to be able to moderate the comments. The Product Comments module allows your visitors to leave comments and you or a store employee to moderate them for undesireable posts. Below are the steps for installing and configuring the Product Comments module in your PrestaShop 1.5 store.
