I was skeptical about ordering one of these after reading some of the reviews but realizing that some people expect a Mercedes for the price of a KIA I went for it.  I have an Iphone and was a little concerned about compatibility, but no problems.  I had it paired up and working in about 3 minutes.  The speaker is very audible even in my 6 year old dodge and I don't have the greatest hearing.  I usually dial my phone using my fingers and I don't think the Iphone even has voice dial so not an issue.  The iphone does give you an option on the screen to switch from the unit back to the phone or speakerphone and back to the unit so I thought that was kinda neat.  For 39.00 this was well worth it!  I used to have a parrot in my old truck that was awesome but also 200.00.....  If you need hands free for under 50.00, this is a great choice.
