I was at the end of my rope with T-Mobile. I know everyone seems to have their own horror stories with various carriers, but T-Mobile had really ticked me off.So, I was in the market for my THIRD cell phone in a year. I was most unhappy with my first two phones (a motorola C223 & a samsung R225), the samsung was decent enough, but it seemed to be ancient by the time the new year rolled around. I decided to get service with Sprint, and noticed this phone was about $30 after rebates. It didn't have a camera, but frankly, if I want to take pictures, that's why I have a digital camera.I got the phone, and the only thing that cheesed me was that it didn't come with a hands-free set (my first two phones both came with one). Other than that, the phone is exactly as described. I've had it about 4 months now, and no problems whatsoever. The reception isn't the best, but it's certianly nothing to complain about.There are several small things I dislike about this phone. The retractable antennae is very delicate, and i've already almost broken it off. They probably have billions of these lying around, and will charge you 10 bucks to replace it. Also, it's a flip phone, and when it's closed and ringing there's no way to tell who it is. A LCD on the outside (like most flip phones have) would've been nice to display the time, or even the phone number. The number buttons are pretty small, but I am a big guy, and I seem to have this problem with each phone I buy.The Samsung 660 is a solid phone, I've dropped it several times, and though it has some small exterior scratches, it's a much tougher phone than other models I've used.The battery life is very good. I've brought this on trips, and as long as I keep my usage to a minimum (2-3 calls a day 4-10 minutes a piece), the battery will last 2-3 days on a single charge. I've found when I talk for 2-3 hours a day, the battery will need charging at the end of the night.Overall, I would highly reccommend this phone to someone. It's a basic no-frills phone with no bells & whistles, just consistant good call quality and long battery longevity.
