I have tried KH a few times after its opening. I find shower water is weak and sometimes not enough hot water.
For software, i think most bg are little bit "pork chop". and compare to HKD, HKD bg have much better quality and service is more 有保證.
KH is good for $20 discount. But I will still prefer to go to HKD. Happy and service is much important than $20.
