Great product with easy battery compartment and large control buttons.
This is my first Vortex bought and I am extremely satisfied with its operation and ease of use.Would purchase again either on new handgun purchases or to replace others. Great sturdy optic and even comes with a protective cover!

Great field of view! I cannot speak to the longevity as it's on my on my daily carry for a few months but so far 100%. This is a Vortex product so we all know about the lifetime warranty :).

Wrong brand item was sent out!
Vortex is one of the leaders in optic they make A1 optic never owned one in my 61 years of owning many firearms. And probably won't own one seeing that my order was stuffed with another brand name! Out of my 15+ yrs. Shopping on Amazon this has happened to me about 4 times! Not a happy feeling at all. When it's your first optic ever! Knowing vortex reputation for quality I have to still rate it a 4-5Star without me receiving the correct item.
