So I have to say stable is the case! But heavy as lead! The iPhone 5s has 112g without cover and shell 294g so it's handy to the shell almost as heavy as 3 mobile phones! This is a matter of taste as the saying goes. I think it's a good thing one notices at least when his cell phone lost ;-) I have deliberately ordered a massive shell because it occurs at the site but often times it gets dropped or you abuts inrgendwo and is because the mobile phone is now very well protected in front of it.
