Right now, anything with a Li battery from FT requires special handling, extra shipping costs, and further delays than normal.
However, their website will tell you what your shipping options are. If they say Singapore post, count on a minimum of 20 days transit time instead of the usual 10.
I have gone a little crazy with them over the last few months and have been hoarding like crazy. All of this new legislation being proposed scares me
I have only had 3 defects: two Kraken clones and a TEC Flashlight mod, and they have made good-probably better than most US suppliers since they credit you for the return postage.
I have learned a few things in dealing with them: their prices are incredible (in many cases 50% less than in the US), they are absolutely reputable with good customer service, and don't order anything from them that you need in a hurry.
On my last order, placed on Feb 5,, I tried to order a little illuminated jeweler's loop with a Li button battery, and even that small item would have knocked my entire order into special handling.
BTW, those Kayfun, Taifun, and Russian clone's are absolutely fantastic RBA's. Just clean them and clean them again, fiddle a bit with the coil and wick set up, and for the price of an original you can buy a half dozen clones. Sorry to the originators, but I have been burned far too often with junk that never worked or broke so often that the repairs were a bottomless pit: Buzz Pro, Joker, Darwin, Fluxomizers. I am still ticked at GotVapes for that last one, since I had a bunch of dry cleaning bills on top of it.
