I tried several brands of remote-controlled sockets, the latter is the only truly valid. Other (ONKIO, etc ...) are always "hard of hearing" and random as it always responds instantly when the four were taken hideout. With me, everything is remote (you must live with the times). Only complaint, catches are not pre-programmed ABCD but it is a breeze to do ... just a few minutes (and a tiny screwdriver) to position the switch's. No small savings, the customer démerde! But I am satisfied because I thought no longer able to find to my regret. PHENIX is a good brand. Be careful if you have a frequency chime, you will perhaps change frequency (switch's 1234) and reprogram all taken ... very simple. You can make cohabit several game made by changing the frequency. One regret ... why not 6 or 8 outlets on the same remote? Only complaint catches are too cumbersome even if less than the other brands. Quality / great price. Delivery flash, thank you that I love Amazon. Believe me, subscription "Premium" is quickly recovered if you buy everything on Amazon (and they all !!!!). I there is no action, but I could not do without me, Delivery on average within 24 / 48h and without signature (no chore in the mail), 1-click purchasing ... sign up! I never had any problems either for returns or cancellations. AMAZON, this is really the best! They all included.
