The best thing about this product is the integration with Salesforce, which we use at work, so it's very easy to get up an running when your project kicks off! It is quite expensive as well - I think the cost would be reasonable if you are using other 3rd party SaaS tools like Box or Dropbox but they don't have everything that Bamboo can offer (e.g., version control).
Sometimes there could also errors in our code because sometimes some components do not support certain languages. For example, it often fails with PHP files even though they compile fine locally without any issues. We're able to manage all source codes from different developers in one place now thanks to their git repo feature; all commit changes will automatically appear in our JIRA tickets once submitted by them.
