1/4 acre sloped but well manicured weed free lawn.  Used Scott's broadcast spreader from big box store.  Functional yes.  Durable and well built?  NO.  Considering it was the only option readily available for purchase at the time when I needed a spreader, I purchased it and put it through three years of service.  It did the job, its downfall however was difficulty in navigating hilly terrain and capacity beyond a 40LB bag.  Also if you tipped the spreader just right at the start, you would spill material and have a burn spot on the lawn.  Dealt with it and began researching the perfect, commercial grade spreader to add to my repertoire.
