The ease of use, it's simple to navigate through the system, and also, I like how easy is to update the warranty information for the various appliances. It's very user friendly, and it's not complicated at all. It's so easy to navigate through the entire product line and find what you need. Nothing about this program makes me dislike it. The interface of the software is very easy to navigate through, and nothing seems too complicated or confusing. I do not have any dislikes with Keep Warranty. It has been helpful in keeping track of my appliance warranties. It was difficult to keep up with them without using Keep Warranty.
