I do not know why this article was of some so poorly rated. The adapter, which I have received are of equivalent quality to the adapters that I get at the big electronics stores here locally. With the difference that I paid here for 6 pieces less money, as well as just an adapter would have cost me at the competition.
The adapter is certainly not meant to intercept dynamic loads, but for static purposes (plug, run), they are very easy to use and therefore more than recommended.
