I've purchased the paid business plan. I need a computer tool to help my customers to quickly decide the stone to use for their kitchens and bathrooms. This online tool saves me a lot of time and cost. Even better, I can virtually custom it fully to my advanced business needs - like uploading my own manufactures' stone samples. Very worth the money I paid for the subscription. Because compared to the money I earned and the cost I saved, the fee is nothing.
