Firstly, the leather wallet case I purchased for my S10 is extremely well-made; it looks great and feels quality. However, unfortunately, I feel the design is almost entirely form over function. The size and weight of the case make one-handed use difficult (and I have large hands), and it's best not to talk about how to actually make a phone call. Another huge problem is that actually using the card-holders totally ruins the profile of the case, spoiling the aesthetic. I wanted to combine my wallet and phone, but it just isn't practical. I can't exactly blame the manufacturer, moreso the product concept. It doesn't work in my view. Just wanted to warn would-be buyers that if they expect this case to actually provide functionality to perhaps look elsewhere. Having said that, the case does look great and is fantastically well-made. Some people will, doubtless, be very happy with the product they receive; unfortunately I can't count myself among them.
