My worry with the guard is that if you land on top of an object it's more likely to tip over...
I dunno. I'm not sold. Hard to say it really helps. That's like me tossing you a bullet proof vest and I stand 50' back and aim 3 feet to your left and shoot. I didn't hit you.. because you were wearing a bullet proof vest lol 2nd shot I aim for your chest but hit your leg. I must have hit your leg instead because of the bullet proof vest. The point? Right place at the right time of impact is what it boils down to. So to say it protected your camera in two crashes is.. null
How many times have you landed on top of any object? Wouldn't this object then hit the camera?
Your bullet proof vest example? You like acting silly

If you haven't had a crash yet, that's great, does that make your silly bullet proof vest scenario null? Really, who cares

lol.
It's a proven "Best Seller" that continues to save people time and money after the event of a crash.
Here's a quote from the Skyreat page -
"QUICK OVERVIEW

Easier & Safer Takeoff and landing (sand, snow, grass, trees, fence)
Clear camera view - You will not see the gimbal guard in frame
100% Carbon -fiber.
ADJUSTABLE and will NOT interfere with the VPS"
Every time I read about even a minor crash with a broken gimbal or camera in pieces, I see a UAV without the camera guard installed. DJI doesn't sell them with it because they really want to sell you a new camera when you crash. It's money well spent and my guard has paid for itself but the choice is still yours.
