Original product is available. Best to check on the warranty availability for your home country if buying the product abroad.

i cannot tell you the price however I did find that the electronics are not cheaper there than duty free the Ipad mini I was looking at was around $50 more in K.L as apparently they had a big tax put on technology a couple of years ago.

Oppo F7... Nokia 7 plus... Samsung Galaxy A6plus..

Sorry - no idea :(

Have never shopped there, so I don't know.

I am not sure since it is illegal they are not showing them to public. You have branded and same item for cheap with other brands name, for counterfeit goods you can check the shops in 3rd floor.

Hi. If you are referring to mobile phones and such, it will be wise to only enter those shops having the same brand name as the mibile phone you are intending to buy, ie; lenovo, vivo, samsung, sony, apple etc. Other shops you are entering on your own risk. It is still better to bring along a local friend if you know anyone here. Always remember, in Malaysia, "Cheap Things Not Good, Good Things Not Cheap". It is always wise to do diligence on the product prices first.
