This is the perfect size for a small family or single.  I love having a covered recycling bin next to the trash.  Makes things much simpler and neater.  I have had this for over 2 years and it looks and works the same as it did the day I received it.  Wonderful product.  You can use regular trash bags as well.  I didn't bother using any on the recycle side and used the 13 g for the trash to save money and time ordering specialty bags.  When I sold my house, the buyers requested my trash can they liked it so much!  :)
