I have one 9 orders from FT since Nov 2013. Ordering mods (mostly vamo and mechs), tanks (puritanks and PT2s), batteries (18650 Panasonic), atomizer heads, drip tips. I normally receive my orders in 2-3weeks (best 17 days, worst 29 days). I use their offered free shipping. In my experience HK Post is the quickest. Malaysia Post the slowest with SG Post being next slowest. If you order batteries your only option is Malaysia Post so splitting your order may be in order. Only used China E-Packet once (8 days from FT shipping to delivery).
Products received have been as advertised and arrived in good condition. On two occasions I have had to return defective product (1-DOA Vamo with bad threads, 1-Vamo threads stripped after about 30 days use) both were replaced and all shipping costs were paid by FT.
If the product is advertised as authentic then it is, if not stated as authentic it is a clone.
I am not a reseller and have no stake in FT, all of the products purchased have been for myself, family and friends. No complaints other than the 2 returns I spoke of above.
The bottom line is I am a happy FT customer. Your results may vary.
Good Luck
