I used it in my Clearomizer.
For about 45 seconds.
Couldn't STAND that flavor and flushed my pipe with water immediately

To each his own ... smokin Grandpa's was like drinking Jaggermeister warm for me. Yilg.
But, for those 45 seconds I got no damage.
I would hope that ePipeMods wouldn't have sold me the sampler with my Clearomizer if any of the sauces they sell would have damaged it, as Katie did a sanity check on the rest of my configuration for me (ordered the wrong size batteries, ordered a stem cover I didn't need, etc).
PS. So far my favorite of their sauces has been a 50/50 mix of the Kentucky Bluegrass with the Georgia Peach. I call it "Kissing Cousins". I'm going to add some Longbottom to the next for a malted flavor.
