The best sandals I have ever bought. I got it a couple days ago and it does not work properly. My preferences are light weight, comfortable, with a heel strike that has some padding. No doubt Ill have to pay for postage or something. In addition to that, the port where you plug the charger in is loose and will not allow a charge. I would highly recommend, wear these in a kitchen extremely comfortable, not cheap but worth every penny. In my experience it worked fantastically with my Xbox one and PS4. This holds more heat in. Comfortable and fits as expected. This is just a small list of the great features this product offers.
