Product review (4 stars): +1 star for good customer service
originally I gave it 3 stars, the pins were bend during shipping. This was very critical for my project, The product it self is very good. I highly recommend it, just keep in mind about the pins may be bent and may be broken when you try to straight them. Buy some headers or just solder wires to it. The seller was great, fast communication and flexible to options. The product comes from China, and was delivered in about 6 business days. If I would need more of these I would buy them from this vendor but keeping in mind about the pins. I hope that the vendor improves in the packing. So far I see the 5 star potential on product/shipping/customer service.
