We made two orders (2 BY micro-ties - LM20) for our go-pro Hero 4. The microphone works very well (although amplifies sound, not sizzling), micro / go pro connection fits very well (no game). The only downside if I find one, is that the foam microphone can be removed. We have an elastic thread tied on top without disturbing the sound of the microphone. As for sellers in glück-express, there is nothing to say: Delivery time, product according to the description. We remain satisfied for the past two commands home.
