I bought it for the price and reviews that users leave here, but after a couple of months of work I am completely disappointed and I do not advise anyone to buy. After about a day or two of work, depending on the load, the points begin to hang. You can connect to the point, but there will be no connection. Or it will hang altogether. I tried different firmware from stable to beta versions. Judging by the reviews on the Internet, they do not work well for anyone. Or they need ether. It is especially unpleasant to overload them when the point is fixed on the ceiling.
