I received by courier, and before opening the plastic case, when I shake the powerboard, there's a pice of something inside making a noise, requested to PbTech to change. They change, sending me a new one (Thanks PBtech, great service!) and the second one, no issues with a noise like said before...BUT, there was a crack in power-board plastic. I don't think that will affect the power board, but I do not recommend this brand, they don't check the quality before sending to the customers.
