Only commercial infused stick I've had is an Acid Kuba Kuba.

I had it at a cigar event a few years ago. I picked it as one of my included cigars BECAUSE I've never had any infused sticks.

I did not think it was bad, at least it was different. But I also have not gone back for more...

More a novelty, IMO.

I've made some Bourbon infused sticks, not that happy so far. Contemplating a coffee infusion though!
