I've been trying to hit their website "fireslate.com" but it won't take me to their site. Their message says visit the website or send $10 for a sample. I'm a little hesitant to send off $10 for a product when I can't even get to their website. Who has used this product and with what pros and cons. Are their any picture of kitchens with this product installed? How long does it take to get?
