Using it for a about 1 week + now at 2 different location , using the RM100 package. My findings

1. speed varies (1 house in bangsar south is consistent at 20mbps++, 2nd house at jalan pudu consistent at 80bmps++ minimum)
2. easy to use except today, it had red light at the MODE section. I believe by changing the DNS at admin section fixed this ( some say this drops the speed as the dns im using is public google dns) . That may be true at before this at the pudu house its at 100 mbps but after dns change is bout 80-90++ mbps.  For me the speed is good enough.
3. Im using it to give internet to 2 laptops, 1 tv, 2 handphones. All no problems.
4. I checked the usage details thru celcom life app - tho the app seems buggy and I feel its not really updating the usage in real time.
5. about 2 hours of 4k youtube usage on my 55inch led tv, took out around 22GB from video walla.

current summary- its something i think ill keep since the portability is very useful when i travel as most times when im in hotel and in house internet sucks to even watch netflix. Im just evaluating now on should i upgrade to the rm150 with 1TB video walla. Needs to further abuse/stress test the service in the next 2 weeks to draw a conclusion
