Have had it 2 months, my only complaint is that the igniters on unused burners activate while other burners are in use. Have tried everything. Help!
Good look

This stove is really nice looking. The only draw back is i’ve Noticed the knobs get hot when cooking on the burners next to them. My old jenn air knobs were down in the front of the burners. Never got hot

I bought this last month to replace another cooktop. I am very pleased with the heat put out by the burners. The surface is easy to clean. It look like it is well built.
