Bud is a friend. I've used a stainless-steel version of the BCG for two years. Pounds have gone through it. It hasn't clogged; turns as good as the day I got it. Yes, the custom ones are expensive and have a long wait time, but for good reason. They use a higher grade of aluminum that any other grinder I've found, and their QC is impeccable. Also, Grinders for Life (the company that makes the BCG) offers factory seconds for significantly less, most of which are considered seconds because of color. If you care about your cannabis and how you consume it, this is a worthwhile purchase.

I have a BCG, actually. I went with the aluminum one and got different colored plates for each grind setting. It was over $200 iirc. I've probably gone through somewhere around 16oz since buying it last June. I think I might be going against the grain here, but there are few purchases in my life that were a bigger let down.

1 it can absolutely still get gummed up to the point of unusability, requiring cleaning. 2 it doesn't grind any better than a Santa Cruze which is less than 1/2 the cost. 3 if you're going to buy it anyway, skip the Fine and Course plates.

This is from someone who used Kannastor for about 8 years until the teeth were ground down to nubs, fwiw.

I really do believe that the higher grade aluminum will last a lifetime though. If my original grinder was of higher quality, I wouldn't have had to buy the BCG in the first place. Too lazy to sell it so it'll likely see the death of me.
