The unit it turns out works fairly well. BUT, mine came WITH NO INSTRUCTIONS! I had to get my daughter to search you tube on how to put the battery in. There was no documentation at all anywhere period. We finally got some from the website and it is ok. Screenshots and abbreviated instructions. No in depth information and a lacking troubleshooting section as I had a combination that was not listed. Abysmal instructions for connecting to a cell phone or tablet but they can be worked through. Also sorely lacking is a lens cover or protective shield for it. There is an aftermarket one, but we are I. The us and it’s in the UK so cost and shipping is astronomical. The company reached out quickly and I am glad, that automatically earns another star just for caring. I will try the links provided and see what happens. Fussing through things the performance wasn’t that bad at night. I am familiar with high end NV and Thermal as well as hybrid systems and white phosphorus based tubes. The look is different, the color is nice, resolution leaves much to be desired. I will have to try it out at the ranch this upcoming week and will have a much better update.
