The flag lock vibration makes it super simple to use. The slope mode is great also. Battery also seems to last quite a decent time.
Vytoov can't be contacted. It seems there is no customer service or technical support for this moderately expensive golf accessory. There was too much information showing.
Weight and balance is good as it feels fairly substantial. Impressed with the new stabilization and just as accurate as my previous tectectec rangefinders.
