Fast connection as soon as you take the earpiece out of the case.
Sensitive touch button, be careful how you hold it, for example if you push it into your ear while talking, it will close.
It does not have noise cancellation, in a windy environment they couldn't hear me, logical. You get what you pay for. I talk a lot during the day, and the battery lasts for 2 days and a little longer sometimes. But, I don't have it in my ear constantly, I only take it out of the case when I'm about to talk.
I recommend it for simple everyday use.
