I tried the free trial. The calculator is a very good feature. I was actually willing to pay just to have that feature. When I got in touch to support, had really incompetent people in support. Kept repeating the same thing, perhaps reading a script. I simply asked how much it cost to have that feature or what package do I need to buy for me to have it. It was talking to a brick wall. I got so frustrated, I turned to another tool and decided not to use Helium. I suggest firing everyone who works in customer services and look to replace people who actually listen and help the customer. Its a shame as you have nice features on your product.
