If you're gonna get it from Taobao, the you may as well get it from Fasttech. It's safer & the warranty is way better.
Its only RM141 for the authentic iStick 50 basic pack.(No cable. No adapter) Its in stock. If you're in KL you can possibly receive it in 8 to 10 days.

Possibly but unlikely. I got a package shipped on the 4th (a Monday) & according to the tracking, they are attempting delivery today. So yeah, less than 10 WORKING days is possible. 

As I've written here a few times. From Fasttech to KLIA only 4-6 days. If you're in KL, you get it fast. I'm in Penang. Pos Malaysia bast@rds only ship to Penang every fortnight. Who knows, in areas more ulu than Penang, Pos Malaysia may wait 3 weeks to deliver.

I use the iStick 50W and I'm happy with it. If you're just getting into vaping then I highly recommend it. You don't need to buy a charger and additional batteries. Should you want to use drippers (RDA) later on, 50W should be sufficient. Fires down to 0.2ohms and battery life is good.
The Subtank Mini is a good beginners tank.

Forgot to add: If you're buying from Fasttech buy the silicon sleeve for the iStick as well. And don't worry, if your mod goes wrong Fasttech has good warranty.

The issues are supposed to be rectified in the current new batch. Anyway there's a number of us here using the iStick 50 without any problems.

Erm I think you should expect 2-3 weeks from the date that FT shipped out. Quite standard for international post because I bought from FT and ebay before also

I believed it stated business days.
