For 1.20 euros that I bought it from Ali, it's great. I've been using it for almost a year now, I bought it to wear it inside the helmet and not miss calls while driving. For speech, you have to be in a closed or generally quiet space to be heard correctly. If you want it for speech, then its battery won't last more than 1-2 hours of speech. As I mentioned before, I only use it to be notified of calls and to hear directions the few times I use GPS, so with one hour of driving per day, it lasts me about 2 weeks. Charging takes about 1 hour, it has its own cable - it's not micro USB. When it reaches the low battery notification, it's already too late, it will shut down in a few minutes, so don't wait for the notification to charge it. If you want it for speech, I would suggest looking for something else. For motorcycle riding, considering its small size that can be comfortably worn with the helmet, for hearing directions from GPS and for being notified of calls, it's OK, but only up to that point... Oh, I forgot, if the contact is written in Latin characters, it notifies me of the call by announcing the contact, if it's in Greek characters, it simply plays a ringtone.
