Xvida is the best
A year ago I ordered a case for my then, brand-new iPhone 6 from Xvida (Xvida.com). I wrote a post about it when I received it praising it's minimalist design and the way it has a family of products that work with magnets for use in my car and at my desk.
Frankly about a month ago I ordered a new case from another company because for some reason the Xvida case had broken in two places on the corners. I didn't remember dropping the phone so I wasn't sure exactly how that occurred. I really did miss the slim design of the case. The one I purchased to replace it was a bit bulkier. So I went to their website thinking I would order a new one and much to my delight I saw that they have a lifetime guarantee on their case. I was elated, and contacted the company to see if I could get a replacement. I was thoroughly impressed talking to Uros, who answered the phone. The conversation went like this" no problem I'll mail you another one tomorrow".
I had already recommended them to a friend of mine, but now I won't stop singing their praises to everyone I know.
I wish every company I deal with would work this way. I don't think they realize that excellent customer service wins lifetime customers.
