Piece of junk - Burris BTH 50 3.3-13.2x50mm Thermal Hand-held Monocular

I have had this thermal monocular for several years now. It worked for about a year and now the picture is blurry. I have sent it back to Burris and they said everything was fine. I tried it again when I got it back and still it is not working properly. I now have a total piece of garbage for my thermal. The Burris company is not standing behind their product. Don’t buy their thermal products.
