Query: Bluetooth car speaker

I bought this bluetooth speaker because of the good reviews, but I was very disappointed. I tried to place this speaker on my car visor and use it while I was driving, but it defeated the whole purpose. I had to hold the speaker in my hand to talk into it. The person on the other end could not hear me unless I hold the speaker and talk right into it. Also the listener complained because they hear all kinds of background noise like I was in the train or something. Only good thing about this speaker is that I could hear the caller really well but that's about it. I thought the price was pretty reasonable, but would I buy it again in the future? probably not.
