Query: One Star is too much, worked twice!

Okay, if you noticed I previously reviewed this as being a great unit. I bought it to travel. First trip it worked fine. Second trip fine. Third trip it just would not load. Now it won't even turn on. So bottom line for 250.00 that I paid for this unit I used it twice. Piece of junk to say the least.!!
