After some tinkering I could use it and the remote control actually works very well even if the plug is behind furniture and if they are spread from one room to another. BUT: 1 / Contrary to what could suggest the announcement, only one of four taken in dimmer function (which also works very hard). 2 / The main shock is no opening for ground terminal! it is necessary to add an adapter to the old, without land: hello safety and aesthetics: we reach 7-8 cm terrain between adapter and plug. 3 / the battery was not packaged in the package so without warranty of not having partially emptied during storage and transportation 4 / untwist a twisted sheet is 5 / a button that gets stuck hacking BRIEF it's still nice but it does not give confidence in the brand.
