I bought the aer disc container when they had a sale on them about a month ago. It’s great quality as always with vitamix. I tried it once but really will probably not use it. It’s limited to what to make with it. I use the vitamix almost every day. I would need a bigger recipe book for it to get me to use it more. I guess if you muddle a lot it would be good. We don’t ever make drinks. But nice addition if you use it.
