Very limited, not customizeable at all. – GoldenLight Review

Great idea. Could be 5 star. I deleted immediately when I had no control over how to define magic hour. I have always used two hours after and before. This gives you a locked in 40 minutes. Maybe good for beginners but very unrealistic for commercial shoots. Nothing can be customized. Great maybe for students to get the concept. Far better to use a real tool like LightTrac . And video maker put their name on this? Btw the way the alarm timer should be automagically be linked to 30 minutes before the customizable default magic duration. To much useless time spent rolling the tumblers to alarm time.
