Great except when emptying.
It is worth having as it can save you a lot of money but the hole where you dump the bag when it's full should be much bigger. When you go to dump it out, you have to hold the hole open, and it only opens about 5" so if you have any insulation or anything puffy you will have to stick your arm in there and pull it out by hand. Almost a great product.
