I like the ability to have a list of all the products in a category, and the ability to compare them. I dislike the fact that the cost estimates are not very accurate. It makes it hard to compare to other tools. It is a good tool to use to create a good list of products, but be prepared to have to go back and forth on the list of products. I am a part of a small company, and we have to use NLPP to track our inventory. It is an easy to use tool, and it gives us a good list of products that we use. It helps us know what the competition is doing in the market.
