I ordered 8 boxes of this tile in April for my kitchen backsplash as I was looking for glass tile that was a true gray and this was very affordable. It was delivered and I opened a couple of boxes to check the product and everything looked good. Unfortunately, due to COVID, I've had to wait to get someone over to install it. I finally secured an installer who started the job yesterday. As he opened the boxes, we found 3 of 8 boxes with more broken tiles than not. Fortunately, I ordered the 10% overage as recommended, but the unusable pieces equal an entire box of tile and is now 'out of stock'.  I tried to call customer service but there is a 45 minute wait and because I received the delivery more than 30 days ago, there is no ability to submit online feedback.  It worked out because my installer is terrific, but it could've been a frustrating outcome.
