Product review (3 stars): As advertised (revised - CHECK to make sure they're not bent or stuck together!)
Looked for a spare set for the ones I bought locally, in case boil overs happen - this arrived promptly and will do the trick.

REVISED REVIEW: Product originally reviewed back in 2014 when I purchased the spare set, and I gave it 4 stars. I didn't need to use the spare set until today (April 9, 2016).  I should have looked at the product upon receipt - but they're drip trays - what could go wrong?  When I removed from the package today, the two sets were stuck together.  I was able to pry apart the smaller set and those drip trays are usable.  The two larger ones, however, were both bent on one edge, and I had a lot of difficulty prying them apart.  Only one was usable.  Thankfully, the larger drip tray on the back of my stove was still usable.  But BUYER BEWARE - if you're not using them immediately, check them out anyway.  I essentially got a defective package, which I'm assuming was returned by someone else.  Shame on me for not checking them upon receipt, but shame on Range Kleen/Amazon for putting them back into the sales process.  So I'm lowering my star rating to 3 stars.
