The range of it (bluetooth to my iMac) goes through several rooms without any loss. Me los he comprado en varios colores y en otros modelos que tienen la misma suela, sandalias de varias formas. Very easy to use and great quality And new towels with it really makes a big difference for the restrooms Good gaming headset, good mic, sub par speakers. The only thing stopping me from going barefoot was the dirty streets of Bangkok that I was walking on. Still giving 4 stars because I love the first one I ordered but the consistency in sizing is annoying. This is probably the only issue Ive had and I knew it was possible since others have mentioned it in reviews. I use these as slippers, they are a bit of a different shape to the clog style crocs but fit my weirdly wide feet well. Make sure you read all of the documentation and know what you are getting and its capabilities so you arent unhappy.
