Well, I hate to report that I found something that Jyarz cannot withstand:
A cat and dog putting aside their differences and working as a team.
Last night I left one of my Jyarz on the kitchen table. This is usually a safe place. We have a cat that sometimes tries to jump on the table, but we also have a little dog that attacks the cat whenever he tries that. So the cat stays off the table.
As I was cutting up some vegetables I heard a crunching, then a pop sound. I looked over and saw our dog chewing on the Jyarz. The cat must have jumped on the table, knocked the Jyarz on the floor, and the dog grabbed it and started chewing. Luckily I noticed immediately, and got the dog away before she ate any of it.
But the Jyarz wasn't so lucky. The glass shattered into a million pieces, the cap was chewed up and useless. So word to the wise, in a battle between a rat terrier's jaw and a Jyarz, bet on the dog
Unfortunately it was completely full, so along with the ruined Jyarz, most of the grind was lost in the carpet
The only bright spot in all of this (aside from the dog being unscathed) is that I really dig that new green much more than the blue that got wrecked. So I guess this gives me reason to order more
Great product. In no way is this a criticism, I just thought it was an amusing anecdote.
