Great product, but is going to 2 years now and I can’t get what I paid for. Paid for green 510c I was send red with damage base which they send a replacement, for the glass full of glue and the wrong color dot are giving me the run around. I fix the glue which cost me a pretty penny. When it comes to the green option I got stock with red which in my condition is useless. We made HOLOSUN out of CHINA a popular product and we getting ignored.
Makes me glad to live on the Coast of Mississippi and don't have to deal with snow and that crap? LOL... Those two days of below freezing mornings were annoying this year. BUT it's back to the 60 I come to expect for winter. I spent over 30 years in Chicago and SW Romania, I'm good for the rest of my life with the whole SNOW thing. One thing this didn't mention, is battery life with the stuff with the replaceable 18650 cells, also whether or not you need the cells with the nipple on the positive terminal. Latter question is too nit picky, admittedly, but battery life is important. Since nothing more annoying than realizing your light is dead when you need it the most.
