Country Pride Large Ultra Slow Feeder Hay Net for Horses - 4 Pack (Black) | Heavy Duty Hay Bag for Grazing Control | Perfect for Stalls, Trailers & Pastures

I have only had these for 4 months so I will update in a year from when I first started using them to comment on durability, but so far only one of the 8 bags I have is fraying at the opening and that is due to user error. I use a big muck bucket to fill these - works amazing, but one of my buckets has a crack and the hay nets can get snagged on that.First of all, I bought two sets of four of these. 4 of them, when I unpackaged them, I crawled inside of like a sleeping bag and thrashed around - to pre stretch the bags. The bags I did this with are WAY easier to fill and I can stuff a lot of hay inside. I weigh my hay - I can fit 40-50lbs worth of a small bale (almost a whole bale) in one of the pre stretched bags. The other 4 bags, I did NOT pre stretch, and they fit a lot less hay inside them - closer to 20-30lbs however, they are slightly slower for the horses to get hay out of. Generally, I put 10-15 lbs in each bag and distribute the hay 2-3 times per day, this has helped tremendously with recovering from ulcers. A slow steady stream of forage has been amazing for the 3 horses I take care of.All horses have received a dental since I started using these and no negative comments from the dentist. The material is not the softest but it seems to be stronger this way and holds less bacteria than some soft nets I’ve used which tend to absorb water and get stinky. I use my nets outside.I’ve tried smartpak nets, hay chix, weaver, and Kensington bags - these nets are super easy to fill with my muck bucket but not so easy to fill without it. These nets have been to most durable so far. And at ~$20 per bag, the best value I’ve found so far for sure. Don’t ever stop selling these!!!
