I must admit, I was skeptical after reading many negative reviews. However, I took a chance as they do offer the lowest prices. Yes, they do not answer their phone. Yes, they take their sweet time to answer emails.
Fortunately, our wedding is in September, so if these didn't work out, I still had time to go to plan B. Well, even a blind squirrel can find an acorn! I submitted my order a month ago for 15 oz wine glasses and it arrived yesterday with no breakage. Also, they engraved our own artwork (map of Block Island) which I uploaded and they came out better than I expected. So, for every bad story, there is a good one. Hope this helps any future buyers out there.
