Hi, am using the skype app both in my personal laptop and in my hand mobile for last three years.
It seems better for video calls other than any other video calling app. Till now I never facing any problem like voice breaking, video blurring, not hearing any voice etc. It is very useful to communicate with my friends, relatives who are far away from me. since they are living away from us it feels that they are very close to us because of that video and voice quality. I really enjoying with this app. feeling happy while using skype.
