We got an amazing deal on IP phones and the vendor included Yealink phones. But one think were disappointed in was how loud the speaker phone was in conference roof type situations. So started looking....for the price, I was like, why not. Ended up being GREAT for us. Volume is MUCH better. The bluetooth adapter worked instantly....did not even have to do anything on the phone, it just knew it was there. We actually can leave this plugged in off to the side of the table and everyone can still hear it. (we do usually move it over to the table just for the mental part of it....folks like to talk at it still.) But for the price, this thing works great. Added bonus....you can use it on your laptop if it has subpar speakers or mic.
