What a pc of junk. We are now on our 3rd one of these. The latches that hold the heating element to the base have broken on the first two after only a few uses. Now the one we have is broken were the probes go thru to the cord. The ribbed design is difficult to clean but it is nice to clean the heating unit. We expected far more from this fine company. Only thing keeping us going is the liberal return policy. Make sure you keep your box to send it back. I think between the three we've poped 10 batches at the most.
