Review on BIJIA Multifunction Hunting Rangefinder-6X 650/1200Yards: Laser Rangefinder for Hunting, Shooting, 🎯 Golf, Camping with Slope Correction, Flag-Locking with Vibration, Speed, Angle, Scan, Distance by Frank Tyrance

I received mine today and the battery was bad right out of the box! Replaced it and figured it all out in just a couple. I contacted the seller for over a week trying to get them to send me a new battery. they still refuse! Guarantee is not kept! They just said to buy one and they would "refund" me! I do not think so! It worked fine with the new battery. So if you don't mind buying a new CR2 battery, you're good to go.
