This iphone case is a hard case, even though it's made of leather: a stiff back and edges of the case mean that the top is open (and indeed how the phone gets into the case at all!). There is no hole on the back other than where the camera lens sits, so if flashing the silver apple logo is important to you, this case isn't for you.
I was worried that the opening at the top of the case would mean the phone slipping out, but it is reasonably secure (it does tend to slide out when putting in the PC connector). I guess this is because of the velvet lining inside the case. Access to the volume buttons is easy given that the top of the case is open.
When the case is on, from the front it looks like the effect of the Apple silicone bumpers, but the leather gives it a much classier look and feel. There is a bit of 'Amazon Basics' branding on the back of the case in the lower right hand corner, but it's unobtrusive. The case does add a couple of millimetres to either side of the phone, but it's not over-bulky.
So in summary - if you want a bumper-style case for the phone, this is a reasonable option that looks good in place.
