Ok, juice is feeding into cup without any atty. A 510 atty works fine, just don't like the taste, that's why I'm trying to get my 901 to work. The adapter and the 901 work fantastic on my silver bullet. When the adapter and 901 are on the mini, and I push the bottle, it doesn't go into the cup, it floods out the hole in the atty. Then it tastes burnt, as of the atty didn't get anything. So confused!!! Now that I've discovered how much better I like the 901 I'm determined to make it work on my mini, or I'll have to sell it. Any more suggestions?? Cheers, leila
