Love the product! A very competitive priced websitebuilder that doesn't overshoot the target by making the tool too complicated yet still has all features customers with basic knowhow require.
The module was easy to setup and allowed me to offer this product to my customers along with their domain registrations. Their initial reactions are very favorable!
