Most have been said already here
Most have been said already here, got myself a 10pcs order as well, for 5 bugs... I was worried, since it's a first for me, creating a circuit, that I possibly messed up the dimensions of everything (and I basically didn't know anything about what could be done and what couldn't). So after fiddeling around with Fritzing, I asked through their live chat if my design fits the rules for the 5 dollar sale. They replied to me saying that I should send them my geber files to a email address that they provided me with. And I got a response within minutes that my design was perfectly fine! So in the end, I ordered 10 of them (a bit overkill, don't need that much, but it's nice to have extra's in case that I would mess up something). I had to pay an extra 12~13 euros for the e-packet shipping method, which is reasonable. I couldn't track the packet when it arrived in my country, the tracking worked only in China. My order took around 11 days to fabricate and around 7 days to ship, which is reasonable as well. I will probably order here again if I want to create something with to much components to do by hand on a perf board :D). Quality of the pcb is in my opinion great, but hey, I am a beginner who's ding this kind of thing for the first time, so what can I say about such thing, right ^^. They do look 10 times better and more sturdy than ones I found in cheap electronic devices from china, so thats a plus!
