Product review (1 stars): Stainless steel screen should stop the bottom from breaking.
Bottom began breaking after 2 weeks of use. Told this is an OEM product so didn't see much use in taking Amazons offer of another unit. I took the refund. Excellent customer service Amazon!  I purchased two 8x12 sheets of stainless steel screen for $7.75 on Amazon and cut pieces to fit the bottom of each compartment. That should do the trick.
