Price and reviews drew me to this product when my last golf GPS quit working. The only drawback I have noticed is that during a round of golf the unit turns itself off and I need to reboot it during the round. The max it will run is 120 minutes before it shuts off with auto shut off. A round of golf (18 holes) will go for 4 hours. I am going to turn the auto shut off in the off position to see if that solves this problem. This is a new item and I may just need to work with it a bit to understand how it works. Overall I am pleased with the product.
