This never functioned properly - ADE Advanced Optics RD3-022 Pro Artemis Red Dot Sight With Multi-6-Reticle System

I was waiting on parts for the gun this was going on so I didn't do anything more than check and see if there was a dot when I got it. A few weeks later I finally got my gun assembled and installed this and discovered it doesn't function. It randomly turns on and off, and none of the buttons do what they are supposed to. It was too late to return it so I went for a warranty claim. It was filed and I received a tracking number, however the usps reports they never even received the package from ADE. I informed ADE of this a week ago however I still have not received a response. Up until this point they were responsive but this entire endeavor is going on two months and now I'm thinking I'll never get a resolution.
