Product review (5 stars): Perfect for my 48-litre Simplehuman trash can (non-compactor)
I have the Simplehuman steel bar (rectangular) recycler trash can (sku# CW2003).  I don't use the recycling bin pieces (which divide the can into two halves.)  I use the whole 48 litres for a single trash bag.  I love this trash can (I recommend it, too!)  The sole problem: Simplehuman designs their trash cans such that many do not take standard trash bags (an obnoxious design feature designed to make you buy Simplehuman bags.)  Mine takes Simplehuman Model U bags, which none of my local Bed Bath & Beyonds stock.  Faced with a special order AND in-store pickup (or shipping charge,) I looked for another option.  Solution: 18-gallon trash compactor bags are PERFECT for it.  They also allow me to really compress and load this sucker with trash.  No matter how full/heavy the bag, it has never, ever broken under the weight of the trash.  Never a tear or a leak, either.  I can put liquids, cat litter, heavy items -- anything at all in this can with these bags.  I can load these bags with 150-200% more (volume) and 300%+ (weight) more than I could with a standard kitchen trash bag.  I have to stretch one corner ever so slightly to fit the slightly irregular shape of the trash bin, but it doesn't weaken the bag.  And the bag is big enough that I can tuck the tails in and get a smooth fit.  When I pull it out, the tails tie easily and create a super-strong handle.

The Husky bags are my favorite trash compactor bags so far.  Highly recommend the quality.
