I just received my High Country Plastics slow feeders, I purchased 6, and they appear to be of very high quality, which met my expectations based on its price. I expect a 10 yr+ useful life for the equipment. It appears to hold approximately 35 lbs of hay (small bale). Assembly was simple and quick. I'm optimistic I will get a two year payback on these feeders. A note - the feeders are 2 x 3.3, or 6+ square feet. In a 12 x 12 stall it is an imposing fixture.
