I had a bad experience with mine...got a lot of choppy calls and such.
I also had many instances where I would be calling a cc company or something get a live person after twenty minutes or so. And then the dreaded " hello"? "hellllo"?
I could hear them but they couldn't hear me.
Yes, my Internet speed was fine too.
Customer service was horrid then too not sure about now.
I ended up chucking it in the trash.
My two cents
