Product review (5 stars): Works well for off-label use!
I use this for under my Litter Robot II.  It works well to keep litter contained and is well made.  My first arrived broken due to -40 (F) temperatures and poor packaging for the weather.  Were it not for terrible winter extremes no packaging would have been needed.  Good product, good replacement from Amazon.  FYI:  For my weird off-label use, I wish it had no pattern in the middle as it makes it harder to set my Litter Robot level.
