Problem from shot #1 - SIG SAUER ECHO CV25 Clip-On 1X25mm Thermal Rifle Scope

I had high hopes. It was great to use for scanning in the dark. But I put it on a 300 BLK abd it shut off after shot #1. I turned it back on & the screen was all "fuzzy" absolutely no way to know what I was looking at. I took a second shot & it shut off again. Same results after 6 shots. The screen cleared up and went back to normal. I swapped out the battery & I took another shot & it shut off again. I took it off the rifle and put it away. I'll send it back to sig & await the verdict. I'll post a second review after I get it back. I'm really hoping I just got a bad one because I really want it to work & be reliable.
