I had a hands-free bluetooth device for the ear before. But, found it annoying ,especially for long periods of time, to have this thing handing on my ear. So I tried this speaker device that clips on the visor of my car. I can hear the caller very clearly and they can hear me clearly, but have to have the windows rolled up and radio turned off. Otherwise the microphone picks up the sounds, same issue with the ear device. But, that is not a big concern and do not need the radio playing when talking anyway. The price was reasonable and about the same as for an ear device.There are a few blemishes that I would like to point out, not deal breakers. The device should, but doesn't, come with a charger for the home. Luckily I own a Motorola cell phone and could use it on the speaker device. Secondly, the flashing blue light at night is very distracting. They need to make it smaller and less annoying. Also the light is impossible to see in the daylight. Would be nice if they had an audio only mode you could switch it to.Great invention and I am very please with the product. Just needs a little fine tuning.
