Query: Sorry I bought this

I purchased this product to get a feel for distance and speed for an endurance horse I'm training. Sure wasted my money on this. Within 2 hours of receiving the product the face fell off. I found that it would not retain the correct date either. I also found that if you don't stay completely out in open spaces (no trees) it does not work. I didn't expect spectacular results but I sure thought for $150 it would work as well as a $10 watch. It doesn't. Don't waste your money.
