I have wanted to try these. They worth $19 - $22?

Meh.... They're good, but they're short and fast.

When looking at $5/ea, there's better options.

If $5 for a 30 min smoke is fine, then yes.

IMO they're good enough that I'd go up to $4/ea for such a short smoke, but really not any more than that. Considering my self imposed limit of $8/smoke, I'd be smoking two of these to make an hour's smoking time so $4 is the cutoff for me.

Only way to find out for yourself is to buy one. I think the first tin I bought was $18, and I smoked one of them. The rest were sent out.

It's a nice addition to add 30-45 minutes at the end of a smoking session when I have just that left before picking up the kids on my days off

They are at best an okay short winter smoke. I've been there I bought 3 tins, gave one tin away, and I'm in no rush to get anymore.
