Mice/Rats can chew through
Keeps food fresh. Plenty of space for a couple regular sized bags of dog food.

Minus a star, because some mice/rats chewed through the bag. Luckily this was only $10 when I bought it.

Just what I needed
The picture needs to be updated because it is a little confusing by the two bags that are different sizes. The 50lb is the larger one. Perfect. Easy twist top but not easy enough for my daughter to get into. You can push out the air and the dog food stays fresh. Easy to take on travel too. Couldn't ask for more.

Great Product
I bought this , because I buy in bulk, and this is working great at storing, dried beans, sugar, flour, etc:) and I love how it doesn't take up much space.

Great space saver
This is a great way to store your dog food so it stays fresh and insect free. It collapes as you use the food which is nice. Just don't tighten the lid so much or you'll have a heck of a time getting it off.

Good item
I've tried a few dog food storage bins and this one is my favorite so far. Has a thick washable lining and seems well made. Collapses as the food is used up - less air should mean less spoilage and allows you to reach the bottom easily. The best part is the lid which goes on and off with a flick of the wrist and has a tight bug-proof fit without any gasket flopping around like some of the others I've owned. And the carry strap is handy and appears well attached. I've had bins on wheels but they were not substantial. Had trouble rolling over anything - including the grout space between the tiles on our kitchen floor - and always threatened to tip over. The reason it gets 4 stars instead of 5 is that the "up to" 50lb capacity rating is a bit optimistic. I buy in 30lb bags (Science Diet small bites) and it fits nicely with about 15-20% spare capacity.

Update 10/10/2008
Today I threw this bag out and went back to using my old plastic bin on wheels. I keep the dog food in my garage and some rodent(s) found this thing and chewed a hole in the side. I tried hanging it up on a hook but this would cause the lid to pop out of place overnight. Don't like rodents and their poop in my house. Not sure I can rodent proof my garage door so I'm eliminating the food source instead.
