Bests & Worsts Reviews from Amazon

I used the Prep 7 once. It was wonderful. The second time I used it the tiny white plastic lever that serves as the locking mechanism between the bowl and cover broke. It seems unusually vulnerable. I have used a Cuisinart CFP 9 for 30 years--loved it and never had a problem. I bought a replacement bowl assembly through e-bay (since to buy it new costs almost as much as the Prep 7) and it arrived with the same tiny white lever broken. I'd appreciate any suggestions, but it's hard to recommend the Prep 7. Great motor. Great everything. But useless if bowl and cover don't lock.
