    A great tool for interactive website features

    Overall: I've used Calcluloid for over a year now and am overall quite happy with it. Users on our site like the interactive functionality, and I like that I can customize the look locally with CSS (great for mobile responsiveness). Good tool - a little pricey, but mostly worth it.
    Pros: You can use custom formulas, customization with CSS, customer support is quick and helpful
    Cons: The platform is a little bulkier, but seems to be getting better. I don't like their payment platform, but the tool itself works quite well
