I have used this app once in my lifetime and I am still regretting it.
Fot eg- If you type Note 5 on google many sites come on the top with varied prices but almost same. But when the name of this site came the price is the lowest of all ans so is the quality.
This is because the goods especially mobiles are refurbished or imported to India. There is also warranty on the products and not even of the ebay.
Though the delivery timeliness is fine as it reaches us 4 to 5 days after placing the order.
Coming to the product quality, it is worst. I bought a Note 5 and it worked fine but gradually the camera blurred and the screen blacked and one day it switched off automatically and never turned on again.
When I called customer care they blamed me that since there is no warranty on the product we are not answerable and please check out in the samsung service centre.
