Mosets Tree has gotten many compliments since it was installed, and now that I look back, I have no idea how I could have got my website up and running as desired without using this component.
Onto the issue of support. I had absolutely no reason to contact their support for several months. The installation was straightforward and the configuration of custom fields etc was a breeze. However, I recently encountered a problem that caused my layout to be broken on certain pages so I decided to email their team for some assistance. I provided them with temporary access to the back-end and had two problems each solved in under 24 hours. Great work, Lee! I had expected to wait at least 72 hours, which seems to be the minimum response time these days from other companies.
I would definitely recommend Mosets Tree to anyone currently looking for a functional and attractive directory.
