These sandals were brilliant and I am pleased to report that I experienced no friction and no blisters. The reception range is amazing. The sound is goodTheyre easy to put on & wearBattery life is excellentThe case is great & easy to see the battery lifeCharges super fast The case is wireless charging so you dont have to fuss with ANOTHER cable if you so choose. Overall, Im very happy with these after just installing them, wish I would have done it sooner. I have contacted Amazon customer service and they are sending a replacement DVD (arrives tomorrow) but I have little hope that things will change. Bought it for my wife as a alternative to her regular nightySHE LOVES IT! I listen to a lot of rap and dubstep, and I used to have the equalizer louder on the highs and the lows for the Sonys and I thought it sounded awesome. I think its a good movie. Mir hat die Reihe vom ersten Buch an gefallen und ich hatte immer auf die Fortsetzungen gewartet.
