Finally after deciding for a long time, I changed to Fibre Internet. Previously, I was paying alone, but now with fibre internet, I can share with other 3 housemates. So with the 10 Mbps plan of RM148, we only ahve to pay RM37 per person per month! It is a GOOD saving.
The performance? OK, we have been using it for 7 months and everything is EXCELLENT. The connection is fast and stable all the time. Although there are 4 of us sharing, but there is no problem at all! And I can still download a file of 1.0Gb size in less than 30 minutes. So yeah it is worth it!
