I have the 1 1/4" hole large bale cinch net and so far it has worked wonderfully. It is recommended to not use with horses with shoes unless you also use a ring feeder to prevent snagging and accidents like the one already mentioned. The first 2 bales I put out this year were pawed to death and stomped into the mud after the bale naturally collapsed, getting that nasty hay out was a CHORE, and I just rinsed it with warm dawn water and hosed it off after that. But I finally broke down and bought a metal ring feeder to keep them from pawing and stepping on the hay, and use a pallet to keep up off the ground and stop from getting any moisture/mold forming between, and I'll never look back. I can put the net on myself, but its much easier with hubby there to help.
Its obviously a bit more time consuming than just putting rounds out normally, but it really does slow my horses down considerably with the smaller holes (the other option is 1 3/4" holes) and my hoover can't just stick his head in the bale and never take it out. He has not gotten heaves yet this year, where normally he would start getting heave-y before the first round of the year was gone. I have had zero waste with using the CC net in addition to ring feeder and on a pallet, and haven't gotten a hole in it yet.
