Yes I have. There are two products that shouldn't be confused: Kingsford Charcoal with hickory (and mesquite) and Kingsford Smokehouse Style Briquettes with hickory (and mesquite). I believe you're asking about the first which is regular charcoal briquettes impregnated with fine wood chips. The second is briquettes actually formed from wood chips not charcoal for the purpose of smoking not cooking. I've used and tried them all... Hehe y'all know me by now.
Cooking with the charcoal w chips smells great and produces good smoke, but the coals burn down much faster compared to regular Kingsford (I call it blue bag) because of the wood chips. So I didn't get the predictable time duration that I've come to rely on from the regular blue bag coals. There was nothing wrong with them, in the end I just found it easier and less expensive to use regular blue bag coals and add my own wood, especially since all my cooks over the past were based on figuring this timing and method out.
Last, back to the chip-formed briquettes.... They are cool and work great. I got a bag free with a purchase of a 2-pack of regular blue last fall, so I figured what the hell ill try them out ... They produce good smoke, and are efficient to use (2-3 on a 30-45 min steak/chop cook, 4-6 on longer 90-120+ min cooks. Are they much different than throwing a handful of chips on the coals?.... No, other the they're compact and tidy for ease of use. I wish Kingsford offered pecan and apple in these products as we'll. Are they worth the $5-6 buck they cost, yah....
Try them all, because of their quality and consistency Kingsford is definitely my briquette of choice and any of their products are worth trying and experimenting with.
Don't lift the lid....
