I bought mine directly from Mac's North American distributor (SmokinLicious) for 33 bucks including shipping. It arrived via USPS Priority Mail in three days.
It came wit about 4 ounces of Maple saw dust and a tea light.
6" x 6" x 3/4"
It seems well made. Lighting with the candle is a bit awkward but it worked.
The handles are nice to have.
I loaded mine with Apple sawdust, lit it, and got 6 hours of cold smoke with no appreciable heat gain in my vertical gas smoker. Of course I did not light the propane at all because I was cold smoking.
The smoulder didn't jump rails, just followed around.
I wished it made more smoke though. Next time I will close the smoker vents completely.
Good low cost cold smoke generator
