i think skynet is very good. cheap, fast and reliable tracking system.gdex is good, but not worth for money.
but yeah,the only thing warped about skynet is the office is closed on sunday.

For me, Skynet is hit and miss. Depends on area.

When I was in Jengka - probably one of shittiest place in West Msia, Skynet was super reliable.
Whenever my package delivered by anything other of than Skynet I will get anxious. that's how good they are in Jengka.

Now I live in Klang, its super shitty. Never in my annals of Skynet delivery in Klang, my parcel delievered on time.
There was one time they cant find my house, and ask me to meet them in petronas 3km from my house. I arrived there, wait for 2 hours. He didnt come. When I call he dont even pick up. He passed the package to his friend that later came to my house in midnight.
There was also one time I purchased RM7 cable from Lazada, and the driver keep promised, delayed and canceled the delivery, every day, for a good whole week.
