free upgrade is going on batches, in Jan 2017 can check for upgrade eligibility, likely that only after April 2017 then can start seeing the upgrade unless TM is really so efficient this round for this upgrade.

are u using alone or it is used among family?

if alone, maybe not, i had shared my reasons in the earlier posts (u can check back the posts) from my own personal prospective since i am a single user for my unifi line. to me, the current 30Mbps is sufficient, next year 50Mbps upgrade will be even more sufficient. of course, everyone is different, and needs different things, so u need to see ur own needs to decide. in the end, rm50 extra is not really a lot and not a big deal given the price we had already paid for, the 2x download speed and 2.5x upload speed for the price of rm50 is really worthwhile, but in the end it depends if u utilize the extra speed given.

if family, are all ur family members heavily consuming the line? such as 24x7 downloading large files or at least majority of time? if yes, it is worth it since it is going to be shared by many people. everyone may be happier given the extra bandwidth that everyone can get despite that it is shared.

u need to decide very quickly i guess. like u said, only less than 3 days left.
