it is what it is...if you don't mind knock offs then yes...if you want name brand then no...
you get what you pay for...don't expect top notch, top of the line for dirt cheap prices...
i've made 2 orders, one shipped and out of that first order had a doa item that they are replacing and sending out with my 2nd order....
first order was here within a week but I did pay the what

$1 fee to have it shipped faster...
but keep in mind that it's not always fasttech's issue of the slow shipping...they are shipping from china to wherever you are so it could be stuck in customs...
but yes it seems to be a 50/50 with shipping speed for people
all I can say as in many other threads/posts read the description carefully...a vivi nova, evod, protank, ect doesn't mean it's the real deal...it's a knock off..unless it actually says the name brand it is not name brand...
but for the price, free shipping and 80% from what I've read good customer support they are worth giving a try and is a cheap way to test things to see what will work for you and what won't and then if you just don't care for fasttech buy the real thing from another vendor of the items you've found you liked.
