VKWorld Stone V3 Plus - Feature Phone In 2017, Is It Worth It?

OK, this one is a bit more unusual and strange, but very functional I have to say and considering it only costs $33, you really cant go wrong. The phone is IP54 rated and is Dual SIM,Dual Standby, it also have flashlight, calendar, sound recorder, calculator, MP3, alarm functionalities. The supported GSM frequencies are 850/900/1800/1900MHz, but the best functions for me is to use the 4000mha battery as a power bank and charge some other device or the super loud FM radio with an old school extendable antenna :-) All and all, I think for the price this phone is great, if you like to go outside off the grid and in to the wilderness, this phone can be very useful, it has a pretty bright LED flashlight as well and with that beefy battery, I am sure it will last more than a week in areas with sporadic coverage.
