Careful, careful, no return policy once ordered, Monitor is very fragile
I order 15.6 inch monitor with built in stand for my Raspberry PI. The issue with built in stand, is that it is so fragile that a slight movement in cables the monitor will move and it can topple breaking the LCD panel. The stand does not help monitor to be in one place, not suitable for regular use.
Be careful before ordering this product as as the company does not accept returns and has not return policy, be careful careful careful.
This is Delhi based company which is importing items from China and selling without any return policy.
