I've been using their RM20 stored value card.

Reason being:

1) It's convenient (you don't need to buy ticket everyday)
2) It gives a bonus trip on the last remaining value (i.e. if you have RM0.60 credit left, that's all you have to pay for the RM2.10 journey)

What's more, lately they are giving RM24 credit for RM20 that you pay

What a cracking deal!

That's a good way to encourage people to use public transport, I'm sure.
