Their tools are very good. I personally have not found issue with Confluence compared with the Zendesk tools we came from.I do recognize that it's very hard to do anything without addons, but that is becoming the norm in IT-development nowadays.But the issues first start when you try and close your account, which is fairly difficult. Luckily, the European data protection laws saved me in this instance. If you, too, have issues with deleting your account with Atlassian because you are the billing contact for a free product, please be advised that you simply have to write to their support and request deletion of the (free trial) products and then afterwards you are good to go.
