I have been meaning to put together a review thread for the splitter, but things have been really busy. I will soon.
The device works wonderfully, and has been providing adequate power downstream to my other USB hubs. I have few communication problems on my gridseed miners now, where I used to need to restart them daily when not using powered hubs.
Its also packaged quite beautifully. Honest criticism is on the power brick, but I typically dislike how big they always are.
Full thread and pictures coming soon.
