Bought a Wosports from Amazon on sale for about $60 a few years ago and haven't looked back. While my buddies have lost and shelled out multiple $300 for new range finders mine is still going strong. Had to replace the battery once over 3 years, range finder gives you battery meter warning. When I bought it I constantly checked against distance markers, my Garmin GPS, and my buddies expensive range finders, always within a yard and usually 1/2 yard of what they are showing. It's obviously cheaper, and I haven't dropped it on a hard surface, but when this one is lost or broken I'm definitely buying another.
