Like many, I was a little dubious about the quality of the GU10 Led came from the other side of the planet. But after several months of use, I can say they are perfect, huge brightness (that was my first concern) and, for the moment, no flashing or extinguishing, it works with the fire of God, I have therefore recommended a new series. Just pay attention to the delivery, not very fast, and packaging, not great, but everything is OK, however, no breaks, NICKEL!
