I like that it's easy enough so anyone in my organization could use this tool without any training or configuration required! It also has an excellent user interface which makes using pull requests very intuitive and straightforward.
The only thing I dislike about this software are some minor UI issues such as having too many tabs open at once when you're reviewing multiple files/pull requets etc., but they've been working hard over time trying to improve these aspects. We have used this product since we started our first internal Github repository back during early 2015. This allowed us to start getting into best practices around how we manage changes within Git repositories by creating proper branches from master branch before merging them onto production environments where testing was done priorly.
