Do not buy these. You get what you pay for. I ordered five of these. Strangely, I received six, five in one package and a second package which contained one single adapter and it was completely smashed. Strange, but no problem, I only ordered five anyway. I connected them and they worked, but then, just now, looked at them under the light. Wouldn't you know, all five are cracked, simply from connecting them. See photo.
