Functional, I like it
The scope is decent. It's mildots are fairly accurate, the internal light has good brightness and adjustability. Simple to install the brackets on the rifle, mounting the actual scope may take a couple tries. Good zoom and focus. Overall good product for the price.

Fantastic value!
Multi featured, low priced optic. Good for target shooting for 10 to 100 yards and possibly more. The 3-9 magnification sells it. Clarity is adequate. I can't comment on durability. Single magnification scopes should be avoided.
