Rick, I thought I would bring this back over to this thread as the topic on the other one was about the Maverick Thermometer and I don't want to be accused of ! lol
Here is a youtube video of the MB Cold Smoke Generator. This is not a indepth video but shows how much smoke it puts out.
yankee, I now have both the AMNPS and the Masterbuilt cold smoker attachment at home. I started with the AMNPS and the wife needed ideas for Christmas gifts. What can I say, I like my toys! I've used the cold smoker attachment a number of time as have the AMNPS and here are my thoughts. They both put out good smoke. The AMNPS would last a little longer on a full fill, but I know I got about 6 hours when I filled the cold smoker attachment about 3/4 the way up. The AMNPS takes a little more effort to light but still VERY easy and fits nicely into the MES30 where it's supposed to. The cold smoker attaches to the side and I'll say is a bit annoying to get it in there the 1st time. After that, you figure it out and it's a bit easier. The AMNPS uses pellets and dust and the cold smoker uses chips and pellets...as tested by others here. The chips are usually cheaper and more readily available. I've found my local box store to have pellets and chips, but a larger supply of chips. The cold smoker attachment is of course easier to reload but the AMNPS rarely needs reloading really.
I'll be doing a pork shoulder this weekend for the big game, and I'm planning on using the smoker attachment specific because I've got hickory and apple chips I want to use. Otherwise, to be honest, my go to piece is the AMNPS.
Did I cover most of the in's and out's of them? Anything else I can try and give my opinion on.
