It's in great condition.
I bought it at a bargain store. I've never used it except to test on my Vitamix. I used the Variable setting starting at low speed and increased. Afterward, I saw no evidence of blade seal leakage. The blade is not loose at all, .. has a nice smooth snug feel. You can view the video here at Streamable.com. A legit video sharing site.
