This is the third that I have used and by far the best. Battery life is incredible and the speaker and mic cant be beat. I use mine in my Saab 93 2007 on the driver's sun visor. I have charged it less than any other device I have ever owned. Can't say anything bad about this product. It is simple, compact and not overpriced. If you are on the road as I am 5 days a week working, this is a great tool.
