Weber Wood Chunks any good?

Yes. 

I use them regularly. Hickory, pecan, apple and cherry. I also use their chips too. I like chips for delicate smokes and as a boost to Long smokes. I add chips to the chunks to give a heavy smoke yo front. I mean, it’s wood chunks. I have had no issues with the size or Quality. There is some variance in the size of chunks, but I like that. I feel like it gives me more flexibility. 

I have tried them and I liked them. They had some good deals in Amazon a while ago and I ordered several bags. 

Bought my first bag a couple of months ago and like them a lot more than the western brand chunks I have been using for years.
