Good product for the price. I like the fact it has the recommended dosages of each ingredient to be effective. All of our horses are on this and are doing well. The other nice thing is that our horses actually like to eat the product. I've got 2 that could pick the peas out of a tuna casserole (if they were allowed to eat tuna casserole) and they seem to like this supplement. If you have picky horses you know how frustrating it can be to buy supplements only to have them turn their nose up no matter how much grain you try to hide it in. Give this a whirl, it seems to have a sweet taste to it and it is effective.

Worked great for a month. As soon as the return window closed I started getting “This accessory may not be supported” with my iphoneX. Still seems to be working fine with my old iPad mini though. Bummer.
