The Sansa View 8GB I received was faulty. The battery would not hold a charge and/or the player would not turn on. This happened within hours of opening the player packaging and attempting an initial full-charge of the player's battery. The battery is only chargeable via USB and I tried using a PC and an AC to USB adapter to charge it. There is no hard reset button like I have seen on other players (namely Cowon brand players) so it could not simply be reset.I decided to return the product for a refund because it did not seem worth the trouble of waiting for a new (or repaired) player. I was not very impressed with the build quality of the player. It felt and looked very prone to scratching or other damage if not treated with extreme care. Furthermore, I found another player that suited my personal needs and desires better than the Sansa View.

I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.

This was a great book,I just could not put it down,and could not read it fast enough. Boy what a book the twist and turns in this just keeps you guessing and wanting to know what is going to happen next. This book makes you fall in love and can heat you up,it can also make you so angery. this book can make you go throu several of your emotions. This is a quick read romance. It is something that you will want to end your day off with if you read at night.
