I broke the tank on my Short DID about 3 days after I got it. It didn't shatter. It just cracked. Ibtanked has replacement tanks, but they don't fit quite as well as the originals. They are a little loose. At least mine was. A couple wraps of dental floss under the o rings is needed. When I ordered my Standard DID, I also got a MM replacement glass for the Shortie. I figured, as long as I had to pay shipping, I'd get the extra tank at the same time.
