Under the "too small" for a con, I am referencing where the Iphone fits into the holder. It is perfect for phones without a case but if the phone has a protective covering the width is not quite big enough to accomodate.
I use this product when I am at my desk. I am on my phone for my job a lot, so I place this near my phone charger and use it to charge my phone. I also love that I know exactly where my phone is at all times!
