Love the concept and I like how it fits in my poket very easliy
Verizon recently started selling this as a standalone (and for $200 too!), so I got it. it's microscopic and I love it! Finally an actually pocket-sized phone! It's great if you're as sick as I am of the trend of phones getting bigger and bigger.
now, in downsizing, they did make a few compromises:
no headphone jack, if you care (I still have a dedicated mp3 player, since my music habit will have me killing even the biggest phone's battery)
no physical volume buttons: you need to use the dropdown menu at the top, or power button for screenshots. I don't think this is too difficult to adjust to.
mediocre camera: passable at best in low light, but otherwise okay.
battery life isn't awesome: I suspect this was actually a conscientious decision: it'll last the day if you're not using it a ton (even without "life mode" which is just glorified airplane mode) so if you're buying it for the whole "i need a phone so i can unplug" mentality, battery life should discourage overuse. Even for moderate use though, it'll still last 8 hours-ish, and heavy use (pokemon go for example), it'll last a couple hours. A lot of reviewers are running battery tests by streaming video on wifi and stuff like that, which means they're shocked when it only lasts a few hours, but that's sort of against the philosophy of this phone). I don't buy into that philosophy either personally, although it still gets me through the day, and i don't mind it being plugged in at my desk.
processor: depending on what you're used to, the low-power snapdragon 435 isn't the most "snappy", but it still does whatever you throw at it.
singular home button: similar to the iphone, we just get one button at the bottom of the screen instead of the usual three (or, you use soft on-screen buttons and give up some screen space). double press for "home", single press for "back", long press for the launched-apps tray. it doesn't take that long to get used to, in my opinion (no worse than moto vs samsung swapping their placement for example)
Overall this is a solid little phone. I have been using it as my primary for about a week and it performs surprisingly well. Most people should use this as a companion phone but I am cheap and did not want to pay the $10 a month. Sim is swappable the fact that the manual says it isn't
For a companion phone it is amazing. Built Strong and Light and it feels very nice in the hand. Audio is good and battery life is whats expected. Last a good 8 hours of decent use. If your a workout type this phone is for you.
