I originally owned model CCJ 500, which after a week of use, would run but reamer would not turn, so returned it for the more expensive model CCJ 900 thinking it would perform better. Didn't even finish juicing the first orange half when the GFCI tripped. Tried it numerous times and it continued to trip the GFCI. Had an electrician check my outlets, no problem. Needless to say, that juicer went back, don't need a fire in my house.
