I had a couple of issues with configuration and access codes timing out, but the support was speedy and amazing, as answers to tickets were posted within several hours in each case with full documentation and even a helpful screen shot.
I had an issue with the overlay appearing behind my sites top menu bar, and assumed it was a z-index issue, but couldnt work out just where to change this. Support was almost instant and fixed my problem perfectly. Could not be happier :)
Thanks for making a review, this is appreciated, all the best with your Projects.
