What do you like best?
Main is its price, or rather there is no price, It totally FREE, also it open source. Bugzilla has excellent community support. It is very convenient that the bug list is also available in the iCal format and I immediately see all the errors in my calendar. At the end of the day, I can see how much I spent on fixing this bug, it improves my productivity.
What do you dislike?
I don't like the weak integration with Github. Also, it has not a very convenient standard review. At once I had problems with automatic duplicate detection.
Recommendations to others considering the product
It's pretty simple, but most importantly, it works and does it well. If you have a small budget, you should try Bugzilla. But first, find a good administrator or a person who has already worked with Bugzilla, this will help you very much.
What business problems are you solving with the product? What benefits have you realized?
First, we used it only to track errors, but with the time we also optimized working processes, monitoring, and reporting.I control the work of other departments and receive weekly reports by e-mail.
