MadShrimps posted a review on the VKWorld VK2015 Smartphone
A quote from the article:
Based on the older MT6582 quad-core SoC from MediaTek, the VK2015 low-cost smartphone is snappy enough for being used with the latest social applications like Facebook, Skype but also for playing simple games as Angry Birds. The chassis has rounded edges and a rubberized plastic back cover, it is easy to hold and be used with a single hand because of the smaller footprint and does not creak when pressed in certain areas. Thanks to the dual-SIM feature, we are offered more flexibility if we use two different service providers.VKWorld VK2015 Smartphone Review @ Madshrimps
