I have been using hefty products and paying their price cause they were better products. I use a large amount of the storage slider bags. I have noticed the quality is getting very bad. At first a fallen zipper every now and again but lately about every 3rd bag is falling on the first slide. This is no5 acceptable. Unless the quality improves I will be changing products. So many companies get your business and do this. I know I’m not the only one noticing this. Hefty you better wake up or all at once your business is again. Loyal User Gail
