Definitely worth the $40. It is simple, yet robust and well organized. Install was easy, and for the most part I figured out how to use it without even reading the instructions. I am not all that technically blessed, either. Very happy with it so far.
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.
This add-on is the best on the market for a portal solution in my opinion.
I have used XENPORTA since its release in XF 1.x series and it has met all of my needs. I purchased the current version soon after it was released and I am very satisfied. I give it the max rating based on its meeting its stated functions at a reasonable price.
That said, it is not "perfect." It does take some work and reading of the threads and discussions to implement its features. Perhaps, a user guide or some documentation would be helpful for others.
