Full of bugs and grammatical errors, slow support, and expensive for what it is. This add-on is in alpha stage at best yet it is being sold as if it were a completely polished final product. A lot of work needs to be done on it and the support needs to improve. The developers need to take their product a lot more seriously, particularly when people are paying almost 15% of the XenForo price for just this one add-on. If the product and support improve, then I will reconsider my rating.
We are not native English speakers, and hope that fixing grammatical errors is not a big problem as the product uses XenForo phrases as it should.
