I always do research before i get extensions to make sure the one i end up picking is A) Stable B) has good support and C) functional to my liking.. Joombah Jobs has hit all 3!
It is very feature rich with very flexible options.. very easy to set up and looks modern and professional.
Although you could get errors or bugs from time to time, they very seldom depending on what you doing or IF you know what you doing.
You can pay for a 3, 6 and 12 month subscription which is not recurring.. with those subscriptions, you get friendly, helpful support in the forums where if you have an issue, it is solved as quickly as possible :)
I am very happy with this extension and i wish Joombah Jobs all the best! Well worth the price!
