Love the gas cooktop and downdraft exhaust fan feature. One of the electronic igniter switches under the knob failed within 2 months but was replaced under warranty.

We have been using the new cooktop for two weeks. We have found it to be everything it was touted to be. We purchased Jenn Air again because the first cooktop was used for 23 years. If the current one will last as long, it will probably outlast me. We are very much pleased with our purchase. It is quick, quiet and efficient.

Nice look and functionality

Replaced my old Jenn-Air electric stove top with this gas version. Works great! So much better to cook on and clean.
