I have lots of dogs and so I have lots of leashes. With these I was able to put one on every leash . Now I don't need to remember to takes bags along. And they are easily reloaded with bags if needed!The bags are crap but the holders work like a charmThis plastic crystalizes quickly. Quantity covered this weakness.I added these in onto my puppy go home packs, when the pups went to their new homes. Flimsy plastic, but they survived long enough to make a cross country flight spanning across a whole day.Works like it should. Bags are quite thin so I put one inside another and use two. It doesn't really matter. I bought them for the holders anyway. I put one on my dog's leash and another one outside the back door where we pick a pool up. Also one in the car and I'm giving the other two away.Good valueDisappointed that an entire roll had not sealed at the bottom properly making them useless and rather frustrating. I haven't used them all yet. But so far 1 of 2 rolls were bad..Im a dog caregiver for my clients I started providing doggy bags and needed some containers for the pet owners that didn’t have. This was such a great value. Really cute easy to open up and refill. The bags they come with age not my favorite but they do the job !
