One very major flaw!.  Be extremely careful not to even slightly accidentally bump the knobs because they will turn on with the slightest press.  I’ve scorched two towels because of this.  So now  we must remember to lock the burners after every use.  I’ve never seen anything like this and would return it if I could.  We purchased in mid-June and don’t use it a lot primarily because I just about hate it.  I think it’s worthy of a review by the Consumer Product Safety Commission.  Would never ever buy this again. It has a lot of good features but the safety issue with the burners negates all of that.  One more thing:  we clean the top every time we use it.  We spend a lot of time trying to get the streaks off from the top.  It becomes a streaky mess even when you wipe it with clean towels.  It appears a “substance’ is coming off from the seal around the top.  We have a new LG refrigerator and dishwasher and they are great.
