I'm giving a try to porn site but I'm really confused between

Zingtube - from xwpthemes.com
Pros:
Good customer service support
1# mradultaffiliate.com recommendation
2# crack revenue recommendation
Cons:
-

Kingtube - from wp-script.com
Pros:
1# crack revenue recommendation
supported Video thumbnail
Cons:
Zero customer service support
The theme crassh when their site crash

I don't have budget to try them myself. it would be appreciated if gentleman helps
IF I Could make Video Thumbnail with Zingtube it would be the winner

I am only planning to buy some script like you , so i can not give good advice.
In my opinion i will go with xwpthemes.
wp-script looks a bit more pro , but you can read feedback about it by simply searching on google or on this forum.
Conclusion is that it most time not working at all. Script license is real time locked to developers site, which is down for a weeks and your site will not work too that time. Also support is almost zero.
This is only my personal opinion after reading many users reviews feedback and so on.

Sorry , i was very very wrong.
I own now these "products" and this is my experience with it :

Do not buy that xwpthemes products - is a waste of money because products are developed with many bugs and there are zero support - emails are not answered at all ,
at official support forums problems are solved or updates released in months in best case.

Only if you are skilled php programmer and can fix all by itself you can try to buy at your own risk.
