7 months review of using it, had some issues lighting up the burner when we first got it and called cosmo, they informed me that since it's brand new, the thermocouple has to be heated up first, after doing the steps, we never had issues with it up until this day. i was so worried since it's my first time owning a gas range. Well, like I said, that's the only issue I had which looks pretty normal, overall, i am satisfied with my purchase.
