I've had the KHV for about four weeks now. What a great device and for the price you just can't beat it. Even though it's considered a mid-range device it's quite snappy and you'll have no problems loading any launcher or game or watching netflix. The quad-core processor will have you covered. So far I've loaded 4 different launchers on the device (SPB Shell, Nova Launcher, ADW, & Solo Launcher). I'm not sure which one I'll stick with yet but they all run great and I have yet to experience any lag or issues with the KHV running these.
I'm also very happy with this device and the battery life on it. I'm getting around 15hrs of use on a single charge with it, which is great that I can go the entire day without having to worry about charging it.
I'm also impressed that I can record in 1080p, Here's a great video of what life is like in the summer here in FL, usually the same time every day and after it's over it clears right up as if nothing ever happened. The KHV is one device that I don't need to worry about getting wet so filming these types of conditions I don't have to worry if the device gets soaked!
Here's also a couple of reviews regarding the KHV. If you have a tween or teen and looking for an inexpensive phone for them you can't go wrong with the this device.
As far as a smartphone that’s available for $30 on a new contract, this is probably one of your better choices out there, especially on Sprint.
