Very good and dedication to customer service

The standard features of the product according to the manufacturer should work without additional power supply, but this is unfortunately not the case with us. If you close it for. B. to the computer, the device only will flash and the computer may not be sent. You need an additional 5V power supply, which costs about 8, which to be reckoned with on the purchase price to do so. This results in not such a good price-performance ratio is more compared to other vendors.

Addendum:
After obrigen review the seller CSL has reported us immediately via email and asked about our problem. Normally on the input cable the necessary 5V voltage should be delivered, but for some reason this was not the case with us. CSL has endeavored to find a solution and sent to us by itself a free power supply. Now does the Switcher. Such customer service you get already rare when reclaims something. But here, the seller came to us voluntarily, solely on the basis of our review. I find that extremely remarkable. That is why ultimately the 5 stars! I highly recommend the seller!
