I bought this rangefinder 15 months ago, enjoyed it for two seasons, but it stopped working last week. Until then it worked very well. The flag finder function was especially impressive. I was 100% happy with the item till then.

When it stopped working, the symptom was that, inside the viewfinder, I could see no lines, cross or numbers. The power was completely gone despite being charged fully before leaving home for a golf course.

When I asked for help, the seller asked a few questions about the symptoms and kindly offered a 50% off coupon even though the 1-yr warranty was expired.

After I purchased the second one at a half price, I wanted to disassemble the non-functioning one to see its inside. To make a long story short, I found a way to fix it. The rubber cover over the power switch is the culprit. The rubber cover could be easily removed by simply pulling it up with a slight twist. Its inside got worn, pinched by the edge of the casing, pressing-down the power switch – i.e., power was draining all the time. So, I put a small piece of duck-tape on the worn part of the rubber cover inside. That made the cover not to be pinched by the plastic casing around the power button, and voila, the rangefinder was functioning again!

I see several reviewers complained about a sudden loss of power and my advice for that is to see if the power button works with a clicking sound. If there is no clicking sound (even though the button goes down), open the rubber cover and do something to release the power button.

This item serves its purpose well and very cost-efficient.
