Bests & Worsts Reviews from Amazon

Pardon me for my long review but at least it is honest and hope it helps other consumers out there. I purchased the product in June 2013 and used it for slow cooking. It had provided satisfactory service until 4 days ago, when I experienced a malfunctioning in the "slow cook" function: the content was cold in the morning when we were ready for breakfast. I tried a second night, still the same thing. I emailed their help desk, opened a ticket. The same night, I decided to see if other function still worked and followed instruction with "congee" and used black rice and whole grain oats in the pot. The cooking was done with 2:10 hours' delay and 60 min of pressure cooking. I decided to go to bed and noticed the "keep warm" button was lit up with "L01:20" on the display (number was increasing, which I assumed it was counting up the time for keeping warm). At 4:30am, I was awaken by a loud "POP" sound followed by constant beeping. I went downstairs and found the grains and mixture was everywhere (on the floor, on the counter and even on the ceiling). All the lights on the display were flashing. It took me two and half hours to clean up the mess! It was scary but fortunately no one was around or could be seriously hurt/burned! I opened up another ticket with the help desk. The representative Mr. X told me to run a series of test to see if the cooker can hold pressure with water and if there is proper vapor release but I told him I did not think the cooker was malfunctioning when it was in the cooking stage because everything looked OK until it went into the "keep warm" stage so his diagnostic test may not tell anything, besides I was concerned about my safety given what had happened the night before. I told him that " I think the problem with the pot was the "fail safe" portion of the design loop. What I saw in the inner pot was burned residue of the grains due to uncontrolled heating. If the temperature was rising high enough due to poor heat conduction of the "crust" (burned residue), the "fail safe" should kick in and shut off the power supply. The fact that it didn't do, and instead, kept heating on and eventually sent portion of the content up in the air, indicated the flaw. Also I believe what happened was the cycle for "congee" was correctly finished, the accident happened when the content was left in the "keep warm" cycle. Why the equipment still kept sending so much power to a pot that was kept at "keep warm" stage is also suspicious." Mr. X then said " If there is a problem with one of the sensors, unfortunately this can not be repaired" and offered to send me a new base, while charging me the whole sale price. I replied to him saying that I believe it is a manufacturing defect that could have severe consequences and I would be happy to give their product a second try, but I feel I should not have to pay for it. Then Mr X replied and started accusing me that " you would not provide a step by step timeline. And to tell you the truth, I don't think you can because you were not there when it happened." "Even if it is a sensor failure,.....Electrical components failing is just a fact of life" and "Your machine worked perfectly for a long time" (Please, give me a break, from June 2013 till today, it is a long time !!??) I was very upset and replied " Do you really think I would be comfortably sitting in a chair sending emails to you if I was there when it happened !?" case unresolved...
