I think currently this is the best budget laptop below $400. Size wise it is about the size of an iPad (around A4 size). The 4GB RAM makes it better and faster than those budget laptops with only 2GB RAM.
From the reviews on Qoo10, it is good for everyday uses such as YouTube, Microsoft Word etc.
Buying from Qoo10 has free shipping, Free Xiaomi Smart Scale and also “Free MS Office 365 Personal 1 Year” Pre-Installed Worth $98. (as of Nov 2017, check the updated terms and conditions to see if it is still valid)
