EXP Tech, they are chinese dudes in germany
I suggest you to avoid to buy from those guys
three weeks ago I bought five boards from them, and they were defective, four missing smd-resistors in each board (which makes the FT2232 completely useless as it's not physically connected), the jtag connectors were cut (which is annoying, as you need to desolder and replace), and the boards look like second hand even if declared "brand new" and accordingly full-price paid (150 euro, in my case my order consists of qty=5, 150 euro each)
I promptly notified all the defects to them, I filled their on-online modules, without an answer!
Interesting … they kept silence for 17 days, at last they have answered me after I have filled a claim to paypal
there is no explanation followed by apologies in the attempt to explain what happened (closed for holidays? congestion? mistakes in the quality assurance?), it's only clear to me that they do not offer a professional service
in my opinion and advice, [u]they must be avoided[/u]!
instead, I am collecting good experiences with dudes of "watterott dot com", when something goes wrong they promptly respond providing an explanation, and a solution, including the free pickup of the defective part, no shipping costs of the replacement part, or the full refund.
We are humans and we all are bound to make mistakes, these dudes do their best to provide professional solutions while those dudes of EXP Tech do not
