These tiles are really gorgeous.  The shipping time was awful with delivery estimates continually extending and ultimately we had to drive 3 hours to pick them up or wait an extra week.  But if you are ordering one box at a time the shipping is very fast.   We also had several arrive broken, chipped or deeply scratched.  However, wayfair made it right so in the end I was overall pleased.  

Everything considered I would feel comfortable recommending these.  And would likely buy again if I ever need slate in the future and can’t find it locally.   These are a really beautiful stone!
