It is pretty safe ordering from FT, as you have Paypal protection if anything goes wrong/missing, and FT do seem to resolve problems eventually (I've not had any issues myself).
Delivery times vary my best has been 12 days, worst was around 4 weeks, though they have had more problems in recent weeks getting deliveries through their shipping companies (seemingly not helped by some poor packing by FT, which I assume/hope has been resolved now).
As far as batteries/clearos go, there's an awful lot to choose from. I've recently bought a genuine Innokin itaste VV v3.0 from them at a great price, and have my eye on a few other Innokin products on their site.
For clearos, if in stock, they have some genuine Kanger tanks and some very good clones - I've tested a few of these, and all are pretty good, though the protank clones with polycarbonate tanks don't all make a connection with my twist and itaste, which is a bit frustrating. All the pyrex Kanger clones (protank, Protank Mini, Protank 2) perform very well, as well as the Evod clones.
I also really like the generic DCTs from Fasttech, and now have 3 of these plus a pack of replacement cartomiser coils
They also stock genuine iclear 16s, which look much like the CE4, but are worlds apart in terms of quality and vape. I assume they also stock the genuine iclear 30s as well
