Any negatives from users? Have been looking at it for awhile. THough not IGC verified it seems to be about on par with Oudie

I've used mine about a dozen times now. Several people told me that the GPS in the iPhone was not accurate enough. Well my first few flights had me taking off about 50-100' from where I actually did. But that is close enough for navigation but probably not comp turn points. So I got the Bad Elf and the accuracy is spot on. The only thing is iGlide will only go into vertical view and not landscape putting my bad elf connection on the bottom of the iPhone. My knee hit the Bad Elf and broke the connection inside. Bad Elf replace for free and now I slid my iPhone up so I would not hit the bottom of it. I also move the entire mount out of the way when I exit. iGlide is expensive, but very nice and very easy to use. And the iPhone 6Plus S is sunlight readable and is mounted perfect for face timing my wife.
