I got two defective units in a row. It was very dissapointing considering how long ago I had pre-payed. However, third time's the charm and this current version has been working for around 2 1/2 weeks very well. I am very happy with it.
One thing I must state, though, that regardless of my dissapointment Entourage has been very good to work with. I really hope others do not have to work with customer service the way I have had to (or like the OP) but rest assured, that if something unfortunate happens (i.e. defective unit) they will do everything in their power to take care of you. That has been my experience.
My hats off to the wonderful women and men in customer service!
