This is the third glass cooktop we have owned, and first from GE; had our first one from 1999-2016, but accidently dropped a drinking glass on it and it spiderweb cracked. Second one from 2016 - 2018, again dropped a glass on it and knocked off corner. Due to our fumbling with glassware near the cooktop we decided to go with the metal edge on the front and back...love it and it looks sharp; hopefully will help in resisting cracks from dropped objects. We love the touch control on/off and Temp control. Easiest to operate. We have the 30" model due to space, and even though we cook a lot this model works well. Burner sizes are perfect.
