No issues with the Crystal so far. It's pretty sturdy. But that's the old 2.0 model, looking at the reviews the new 3.0 is a downgrade in terms of quality, in addition to the downgrade of being forced into the proprietary cylinders
Bummer. I loved the glass bottles in the penguin, but I got tired fighting the durability problems. I got as far as researching custom gaskets and shims, and gave up.
