First of all amazon is great online shopping website
I made many purchase from amazon till not I did not get any defective product
Recently I orderd 3D glass from amazon it was around Rs 280 including shipining charges though the product was came same as mentioned built qulity was good but unfortunitly I have returned the product because the 3D class were not compatable with my laptop so I returned the product and next delivery boy came and took the product and went and after 2 days I got my refund amount back to my bank account
They really provide quick and easy service
