I love your clothing and delivery If you have an existing controller, all you have to do is map the wires from the old one to the Rachio. This is a simple yet genius product that works great. I use these mostly to remove bright red or dark lipsticks, multiple layers of mascara, or dark smokey eye makeup to name a few. You will not be disappointed - Im going to buy a second pair before everyone realizes what a bargain these are! They fit okay but not as well as the women?s reggae sandal that I usually buy. I really really loved the sound of these headphones for their price and size but I am very dissappointed with the quality Ive experienced. Also, the magnetic headphone pad fastenings have gone- replaced by a clip on system ? this is also probably to do with the provision of ANC but may be a tech rather than a cost issue. Purchased these sandals for kayaking. Perhaps his will last longer.
