Upgraded Airtronic B4 with this, I believe latest generation burner, so managed to skip one generation haha. Way easier installation with all pre-wired plugs. Took way less time to install this, but probably due to experience with the first one and all the holes already drilled. Otherwise really happy, it is truly quieter now. Satisfied with the purchase.
