buying there is a gamble.
If you're prepared, you can get a great bargain. First thing you do is to know what you want. Research, research, research...
Know what you need to look out for (dead pixels, etc...)
Check everything and take your time.
And, once you get home. Check everything again. If you have any problems go back immediately, do not wait.
Got my K610i there last year. Bluetooth did not work, went back next day, they replaced my unit. Okay pa naman hanggang ngayon. Got it for about 3K less than the Vmall shops.
