Fantastic, was the best portal addon for XF1, and still is superb! Easy to use, and does what you need it to do. It now uses the built in widget system in XF2, which makes it much easier to use other widgets with Xenporta. Excellent product for the reasonable price tag. If you need a portal solution for XF2, you can't go wrong with Xenporta.
Fixes necessary bugs, but support isn't exactly great. Often snarky comments and one liners (which are not helpful) when customers have reasonable questions about the product. As for adding new features, don't hold your breath.
Overall: Even so, the pros outweigh the cons, especially if you have some XF skills of your own, which limits the need for support (outside of obvious bugs).
Overall rating: 4/5.
