I have been using the Preethi Chefpro plus for the past ten years . The small jar has given me a lot of trouble and frequently broke down and had to be repaired. Even cracks started to appear in the jars, not very good quality. But the larger jar is working well .The plastic containers are easy to use although we should make sure that the size of the plastic container and the jar(in case you get it replaced) fit each other properly. Overall its not a very bad product but not too good either. apart from these frequently getting repair problems it is easy to use and handy .
