It's very easy in using as it helps us organize our work easily without any hassle or confusion.
Also I think they have made everything clear so even newbies can use them well. The only thing which i dislike about prodpad its price but not much though still if you are looking out something cheap then go ahead otherwise don't waste your time because there won't be anything good enough when compared other tools like JIRA etc., Nothing really bad except their pricing factor nothing else just try once before buying and see how helpful will get after usage!
