I got a Captain Crush in 2015. It generally worked fine for a while, and then started to go downhill. The free rollers wouldn't spin, and going in reverse often wouldn't help. I'd have to dump all the grain out and move them around with my hands until I worked out all the grain and dust in the rollers. I wrote Northern Brewer about it earlier this year and they noted a couple of things. First, they said the set screws might be stripped. Second, they noted "All three roller mills can jam up a little, part of the trade off for fully adjustable mills that have different rollers to first crack, then separate the husk from endosperm." I don't know what they advertise now, but when I bought it all the marketing was about how three rollers are better than two. If I get a new mill, it'll be two rollers, and probably from Monster Mill.
Regarding the set screws, they were stripped. They were likely that way from the beginning because my knobs never clicked when I wanted to change the settings. I had to loosen the screws and then turn the knobs. I didn't realize they were supposed to click until I started having all the problems this year.
NB sent me new screws, but it didn't solve the problem. I decide to completely take apart all of the mill. It turns out, the powered roller was inset into the housing of the mill, causing resistance. I fixed that and also added some olive oil for lube where the rollers sit in the end plates. After that, it worked great and I had no problems. For about four batches. Now those free rollers are starting to be less free again, but I think it's mainly from build up of dust that I'll have to clean out.
Overall, got it broken, then it broke further, fixed it, now it's slowly becoming a pain again. I'd recommend against this mill.
