Product review (4 stars): Warped like crazy on the first use!
Warped greatly on the first use.  Part of successful broiling requires that the food lays flat and is the same distance from the heat.  That is not possible with this cheap broiling pan.  I will probably never use it again.  Makes me wonder how other reviewers here raved about it's quality and mentioned that it did not warp.  How much did it warp?  Two of the corners of the rack were warped upwards at least 1" from the pan.  That's ridiculous.

UPDATE: I have used this pan several times again since the first time and for reasons that I can not explain, the pan is no longer warping during use.  Based on this, I would now recommend this broiler pan.
