Definitely has saved me from bursting my earphone charging case Overall, a good shoe, but if you have a wider foot, you might considered a different style. Hope next will live more than 3 months. Very easy to pair. Das Produkt wirkt wertig und funktioniert wie vorgesehen. Thinking about buying a third one to use for our friends when they visit and need a little battery boost! Then suddenly after 3 months of use, one channel just stopped working. These shoes are really cute and comfortable. BUT they tend to get me through the cooler/cold months before I have to replace them, which is better than most slippers you wear a lot in winter. I?ve only had them a short time so I may find an easier way to work with them as I like the way they fit and they don?t hurt.
