Excellent. I still don't try them sleeping but I already tried the pattern of lights that comes by default and it does show with my eyes closed!! I think the same seller recognizes that they are not the originals, but if they are not, the truth is they are very well made and I could swear that they are, even the instructions that come is of great quality and with very clear instructions. I need to try programming it from the website and obviously already asleep but the truth is I am super happy with. The purchase, super recommended. For certain the delivery was very fast!!!. Thanks to the seller!!!
