To be frank, I think there is a lot wrong with the design of the sticky card holder that I have on my phone. It can only really hold five cards, wears and tears easily, can’t scan cards through it, and can’t easily take cards out of it. However, despite all of the flaws that become apparent after substantial use, I still use it above any alternative because it’s so convenient. Convenience can often be a misleading quality of a good design, but in my circumstance, as a busy and forgetful student, I find it absolutely essential. My phone is the only thing that captures my attention all day, so I’m more likely to notice that it’s missing before I notice that my wallet is missing. This product easily fits with my lifestyle, which is why I love it.
