This good quaility product is rugged, easy to install and easy to read. For long range shooting is is very important to maintain a level hold to insure the most accurate shot! this product helps you do that without breaking the bank!
Inexpensive, works, but would prefer rounded corners. Those who say they can see it in their off eye while looking through scope must have one eye on a tentacle! I can't see how it's possible otherwise.
