We had an AG Jade range, w/ sealed burners and returned it as soon as we could. The knobs were way out of whack (supposedly a well-known problem to many in the appliance business), the oven wasn't calibrated correctly (even after an attempt by the service tech), and the burner caps spread the flame out too far to be used at full power (or even close to that) with all but the largest of our pots/pans.

Also, at the time, Maytag was looking to sell off the Jade range division and/or that Jade was looking to discontinue the residential ranges. We were afraid of being stuck with a problematic range with no support, so we did a buy-back.
