Hi! Sorry for the late reply, we've been very busy with the Kickstarter Launch. They will definitely stay in place, this was a major feature we worked on and they hold really tight (they are even a little hard to take off, but that's the price to pay

).
One of our stretch goal is a custom Tempered glass that will fit perfectly with Ecke.
Check the video, we have some pretty hardcore drop tests too!! My toddler loves to throw my iPhone around too...But I never got to film it LOL. Here is the link to the campaign:

Best regards,
Nathalie
