Query: Only works on High Setting

I've tested this twice and it only works on the high setting. Not great for slow cooking! I wasn't sure at first because I always start it on high and then go to low, but it definetly doesn't work on low. I bought it this summer and didn't use it at first, so now it is too late to return it. Make sure you use it right away a few times, so you can return yours if it is junk.
