I've owned 2 Grove iPhone cases, and I love them to bits. So I was kinda glad when I knew I don't have to change cases for the iPhone 4s.
I put up with them breaking if dropped on hard surfaces.
I put up with them having small port holes, so I have to remove the bottom slider occasionally.
I put up with the earphones hole being small for my in-ears, by getting a Shure mic adaptor for iPhones.
I put up with all of the above because of the look and the feel of the bamboo. I've tried holding 'metal', plastic, and silicon ones. It just doesn't have the nice cosy feeling of holding a Grove. Other wood cases are bulkier than the Grove, and when you put in all the values of the Grove Team, you can't fault the quality product, manufactured with meaning, and heart.
