what u saw? can explain please 

I agree with bro CK - it depends on where you live.
I am currently living in one of the landed GnG project in cyberjaya. Good living environment, superb security, quiet and slow lifestyle but yet not too far away from happening place like puchong. Food variesties mainly restaurant or cafe however no traditional kopitiam yet. No traffic jam, no parking issue not so crowded everywhere you go.
End of the day, depends on your lifestyle.

U looking for high rise or landed? Budget and how urgent u want to move in?

Crime can happen anywhere and to anyone. What you need to do is to be always vigilant and be aware of your surroundings. I have not heard any one taman or township that has zero crime rate. Just me personal opinion. Anyway I am planning to stay once my house is completed. On 1 hand I can't wait on the other a bit nervous coz need to get used to seeing non local faces almost everywhere you look. But I think after a while already lali

Same like bro CK15, I've been living in CBJ for years already. Been from "live study play" to "live work play" at this same place since I move here to study years back. Really enjoy the calm and peaceful life here. Rather than stuck in the jam after work, I drive home in breeze I can utilize the extra time by cooking at home or jogging in nearby tracks and nice lake gardens in CBJ and Putrajaya. Sometimes I even jog or cycle around the neighborhood at night without worry. I have seen many Cyberians did the same too, much healthy lifestyle here I would say. I frequently see police cars patrol around CBJ all the time, day and night. It helps to make u feel safe and secure a bit 

So far I have not encountered any disturbance from foreigners and other crime related situations *touch wood*  Maybe because I avoid going to those places as mentioned la. I'm currently living in an condo with many foreigners students, so far still doing great by minding my own business. U may hear bad news coverage about those foreigners once awhile, but really, not all of them the same laa..  so just chill!

As for food choices, it's getting more and more so no worries. But don't expect chinese stalls or warung melayu to be opened here la, the lowest range of food u can get here is economic rice and mamak. U can easily find mid to high range food in CBJ. 

Buying landed bro?
