My wife and I switched to Sprint on their 4 line promotion. A major reason for that was to bring my older brother and 91 year old mother into the 21st Century. That is, they have never had cell phones. My brother was planning a long trip, and my mother still drives, so we were concerned about both of them. However, we certainly didn't want to spend a lot of money for the phones. Turns out, we didn't. With Sprint's promotion, we got 4 lines for the price of our usual 2. (Beware, though - that promotion ends 6/18, and God knows what the service will cost after that.) The J3's we got them were on promotion, too, and they wound up being FREE! Certainly can't beat that! But, free phones???? Frankly, in working with these phones to prep them for my family, I was surprised at how substantial they were, and were like any good smartphone. Did not appear in any way cheap or chintzy. While I'm not the one using them on a daily basis, they really seemed perfectly fine. I can't comment on their performance, but I can say that they seemed lovely, esp for the price. If this were my first smartphone, I'd be perfectly happy to include them in my shopping.
