TLDR: they are 100% worth the money, I'm seeing less wastage, and not having to fill it as often. My horse can graze on it, instead of eating it all super fast and wasting or dropping half of it. Good enrichment for him as well, and keeps him out of the rain while still able to graze
I have been around GutzBusta haynets before, however never used/ owned one myself until recently. As we all know, hay is becoming scarcer and scarcer due to the Victorian droughts. I myself was in a position of buying hay 10x more expensive than this time last year. It's been very hard, and have had to find ways to combat wastage, as every stalk counts. I considered the GB haynets for a while, and finally bit the bullet to spend the little bit extra money for them, based on what I'd seen/ read about them. I used their handy guide to find what would suit me/ my horse best, and went for the 3cm holes, and a medium size so i wasn't having to fill it so often.
Wow. thats all i have to say. not only am i having to fill it less often, I'm also seeing almost no wastage (apart from the grass seeds that fall through the bottom - but prior to using these haynets, i was losing the equivalent of 1/5 of a square bale/ per bale used, which is definitely not ideal!) He eats it much slower, meaning the hay in the net is lasting longer, and I'm not going through my bales as fast as i was. I'm also able to secure them on tree branches in a way that theyre free-hanging, so that also slows him down.
I whole heartedly can say that these are worth the money. I am not sponsored, nor being asked to write this review - as someone who relies on reviews to know if a product is worth buying, i thought it would put my honest thoughts out there for someone who is the same as me. I will definitely be buying more in the future, should I ever need to.
