Excellent. Easy to use.
I've used SandClear for years--easy to use and a bit of insurance against ending up with a horse with sand colic. Corro has very competitive pricing on their products and free shipping when you spend $75 or more so in the past year they've become one of my favorite sites for horse products.
Use this all the time
I shopped around for cheapest Farnam sandclear and Corro, beat everyone else's price. Thank you. Its expensive to own a horse, but you make it a bit easier!
