Not suited for a stated use. - SiOnyx Aurora 1-3x16mm Black Night Vision Monocular

I purchased this as a night vision co witness to a rifle optic. The item arrived without a user manual or the imaginary quick start guide. It was apparently and open box item that had been returned before. I downloaded the owners manual and the quick start guide. Followed the instructions carefully. The batteries were not up to the job. The first one took about 14 hours to indicate full charge. The second took 4 hours. The first one lasted about 30 minutes before going dead and the second just under an hour. After downloading the app and getting it to connect to wifi the app said camera not connected at the same time in the viewfinder it said connected. I made multiple attempts to get the app to say connected without success. It did show the wifi icon as being on but could not use the app because of the false not connected at the bottom of the screen. Since this was billed as usable on a rifle I also purchased the mount. With the mount attached to the unit you can NOT change the battery. If it is mounted on a rifle you must remove the entire setup from the rifle then remove the mount from the optic to change the battery. I could go on for a few more pages but I've had enough of it.
