I already have a pair of Deco M9 (given free when I signed up for Myrepublic's broadband package) but there is a deadzone in my bedroom so I decided to buy a pair of M5, the older and hence cheaper model. Coverage is lesser but my apartment is small so all good. Super pleased now as wifi connection has improved in the bedroom!!
Purchased off Lazada recently and I believe the sale price is still available. Adding each device to home network was a breeze with the TP-Link Deco App.
