Haven't tried it yet but am so excited to!  I've been needing a proper lasagna pan for awhile now...because no matter how hard I try, it just doesn't come out right if the pan size and portions are off!  Came across this and had to try it!  It's just me and my husband, so this gives me the opportunity to make different lasagna flavors and/or portion and freeze easier than using one big pan.  It's big...seems like each chamber is legit 1/3 a proper lasagna pan size.  Seems like each chamber will fit a lasagna noodle just right.  I have a feeling my husband is going to like the fact that everything is an "end piece" :)  Cleaned up well and non-stick coating seemed pretty slick.
