Ya correct, it's the 7-year rental plan, this promo also applicable for 5-year plan, the price will be RM80

We haven't receive any marketing material on this promotion yet, so far only the internal memo that inform such promo
Cannot, once signed, u are bound by the contract, so must fulfill the whole 7 yrs or 3 yrs (if u are on 5-yr rental plan) 

I think so too, so i always recommend going rental plan

U pay a bit more (RM240 over 7 years), but u get 6 more years of warranty, i feel it's a better deal

With current WD516 RM50/mth promo, u actually pay less with rental than outright purchase
