Bests & Worsts Reviews from Amazon

Delivery in 2 days, new factory unlocked phone in un-opened box with all accessories advertised. I'm in rural NW USA, did a speed test and got data speeds of 3mb/s on sim1 AT&T, not sure about sim2 H2O yet. You have to choose witch sim you want to receive data from, not both at the same time. Edit: After a few weeks use, I noticed the battery life on this phone is very good. I can normally get 12 hours standby with checking emails a dozen times or so and a couple phone calls, checking out a couple web sites, etc. and still have 80% battery left. Checking speed test in the city (Seattle) I was getting 6mb/s. The dual sim function allows me to carry one device for work and personal with different ringtones of my choice, work and personal email, text and calling. The 4.2.2 software works seamless with no lag on common apps. Haven't tried any games although. Edit: Over a year later, still satisfied with performance, reception, wifi and battery life. Dropped it on a wood floor once pretty hard and the cover partially popped off but clicked it back on and it still worked fine. Samsung recently pushed OS update of Android KitKat 4.4.2 for this phone that works without a hitch. I did encounter a flaw in the stock Chrome browser although, in that it can rarely on occasion stop responding. A re-start of the phone brings it back to normal. Also, calls made are defaulted to sim #1. If you want to call from sim #2 you have to swipe down on the screen and touch sim2 before you dial. Not too much hassle but with the last OS, you could switch sims and it would stay on the one you picked. I also wish the ringtone was a little louder as I work in a shop environment and rely on the vibrate. Over all I'll still claim five stars.
