I try hard not to drop my phones, but that's why they're called accidents. Dropped just twice in each situation what's really saved me is the slim armor case I use. These are the best cases, they're just incredibly durable, comfortable, and good looking. Best of all is the protection my phone is still perfect and there’s no marks on the case due to its rubber corners and ends.
They retail for $30 which is a good price, yet I get them from Amazon for under $15 an amazing deal.
I've spent a small fortune on all kinds of quality cases over the years. But having found the Spigen SGP Slim Armor, it's all I buy for my various smartphones. For a two piece case the quality and fit are perfect.
