$2000 junk - FLIR Systems Thermosight Pro PTS233 1.5-6x19mm Thermal Imaging Weapon Sight

I wish I could give this product less than one star. This scope zeroed easily in 45 minutes. The next time I tried the scope (hog hunting) the batteries were dead. I went home and put new batteries in the scope. It worked correctly so I turned it off, and then the next time I went to the woods the batteries were dead again. I had spare batteries with me this time, and when I put them in, the scope worked. I killed 3 wild hogs in less than a half hour. I turned the scope off and the batteries were dead again the next time I tried to use it. The scope has never worked or powered up since. It is completely dead. I have tried several brands of batteries and called customer service for advice. The one time I got a person on the phone, I was told the 233 has a long history of power switch problems. I have now shipped this useless waste of money back to FLIR for warranty repairs. FLIR customer service is difficult to get on the phone and never return calls or emails. I have 2 other FLIR products that work flawlessly, but the PTS233 is junk. Definitely better options from other brands at this price. DO NOT BUY
