I use several boxes of these bags every week and I have never had one break or tear. I had problems with other brands of bags of a similar thickness and price range where the bottom bursts open upon lifting heavy loads. I am also able to drag them across the ground without spilling the contents.
I do a lot of demolition and construction and normal bags just don't cut it. They generally tear about as fast as you fill them but these bags are pretty tough. I've hauled loads that challenged my strength they were so heavy, the bags have always held up, even if something managed to push its way out the side of the bag they still do there job.
I have a machine that vacuums, mulches, and blows leaves into a bag. I transfer these mulched leaves into the contactor bags and keep them outside until Spring when I roto tiller them into the ground. The contractor bags are very durable.
Pros: Durable, Easy to Use, Sturdy, High Quality, Good Size & Weight
These maybe pretty expencive but are really tuff. Great for those jobs where a regular liner will not work. I have carried a 30 pound bag of broken tile shards up a filght of steps with these bags yes the points poke through but the bag held together long enough to get to the dump some months latter. I always have a box of these on the job site. I keep Glad bags for general trash but if i'm cleaning up something heavy or sharp out come the Huskys. I couldn't do without them.
We do a lot of Demo's. It's important to fill up these bags with as much trash as possible without breaking it. This product is made to open easier, to not split at the seams and to hold more than you would think it could. That's a lot to ask of a plastic bag.
These bags are a tremendous deal. They don't tear, are easy to fill. You have to watch the weight you put in though, because if you make to too heavy the trash collectors won't pick them up. They stand up to a lot of dragging and tossing.
