I would definitely recommend this lock. We also took it to a shop to get it installed by someone else because we didnt want to risk anything actually falling off. While other headphones are plastic, these are metal! I am also impressed with the microphone holder. I have been wearing these slippers/sandals non stop since I got them a week ago. There are several reviews that say that these came out of their wall. 6) instantly saw both the wifi and bluetooth without issue. Hasta ahora 4 meses de uso y funciona excelente. Charge two dollars more and include a brass one. The emblem on top of poohs face is kinda fragile and easy to come off.
