When my iPhone suddenly died, I bought a used one from them. They have a reliable, long warranty/repair period for the used phones they sell, which is good peace of mind. When it turned out to have a small issue, I took it back in and they diagnosed and fixed it with no hassle or charge at all. I now have a 100% great working phone, for much less than I would have bought it elsewhere. They definitely know what they are doing, plus they're friendly and respectful, and am glad I went! Thanks guys!
