Great cage liner, but should be changed every 24 hrs
I purchased four cage liners and they work great.  I change the liners every day-If I didn't the odor would be horrible.  Just sweeping up the poop does nothing for the smell.  It's the urine odor that is horrible.  I have two guinea pigs just to give you an idea about the amount of waste that they produce.  So.....Changing the liner every day is paramount for me.
