Inexpensive, arrived in less than 2 weeks. However, buyer beware before plugging it in. The male plug and female socket on mine were soldered on backwards! You can clearly see in the product photos that the female socket should be on the input side. However it was on the output side. Not too big of a deal, just annoying. I had to unsolder both sides and swap them.
