I needed something free for a church website that I was doing for free. Their previous web designers really dropped the ball and they didn't have the funds to get a new place in. Material Kit looked absolutely stunning by giving a modern look without looking sterile as many designs tend to do. It was really important to feel modern and warm. I cannot recommend this enough. Since then I've started buying from them to both support their work and to get access to the pro benefits (specifically access to the scss files for superior customisation). Remember, for most people, the free is more than enough. but the premium is worth every single cent too.
