Defective DMT

I have a DMT D8EE and the diamond surface is bubbling up and breaking off. The bubbles are easily visible but you can see where its peeled off. It is very hard to see unless you reflect light off of it in different directions. At first I thought it was just very small rough spots on the hone but they just got bigger as i tried to wear them off with a kitchen knife. I called DMT and they told me to send it in for inspection. Just a heads up to all of you who own these. Does anyone else have this problem?

BTW, I have had this hone only about a week!
