Well, I'll ad my experiences with FT..... they don't list my first purchase from them, a Vamo V3 back when it was new.. probably about 2 years ago. since then, I've spent hundreds of dollars to them through $50 increments... I've had only about 3 RMA's, one was a missing chimney from the Protank II, another was from an overly leaky Squape-R.. for the first, they sent me a replacement tank, and I kept the old one. For the squape-R, they had me ship it to their Florida warehouse (?) and they sent me a different version as per my request. There was another insident where they shipped me an extra drip tip, and another where they shipped me a second Kayfun lite... Yes, I was honest enough to buy the second Kayfun.
Their customer service has been fairly prompt considering they are on the other side of the planet, and on opposite times. Their shipment dates are somewhat accurate, but they have been known to go over their estimated "arrives in" dates, but so far, not much longer than 3 days. when it goes over, they split the shipment and ship what they have so far, and will ship the remaining stuff as they get them.
Considering where they're at, I have no problems with them and think they're one of the better overseas companies I've worked with.
Another competitor, I ordered during one of their "group buys"... it took over a month for it to ship, and was not provided a shipping number. It did arrive about the same time, but if I had to go somewhere, I didn't have any way to guess when it would come in.... Currently I have another shipment waiting from another company.. I bought some batteries that were on sale.. the website said they had 200 of them left.. but when the 7 days shipment time came.. they didn't have the batteries... they just issued a store credit.. which took another 7 days to get back to their account. I won't be buying anything from them in the future.
So, from what I've encountered from other companies,
fasttech has consistantly delivered, and has been straight forward in what they sell. Just keep in mind, they are a reseller,and sell both junk and good stuff. read the reviews.. they don't withhold any unless they mention a competitor..they'll even post messages with people making fun of the product... to me, that is crystal clear and no censorship. IF they know it's a clone, they will say "like" on the description... if it's authentic, they will post authentic. They seem as honest as any shop owner can be.
