I needed this for College! It had a very hard time starting up the first time. I let it die one day and it never turned on again. The bottom gets so hot when its charging. I can't even return it.Contacting the manufacturer for the warranty has been a nightmare! No one wants to help. Don't buy this! I wasted so much money on something that doesn't work and now i'm stuck! No money to buy a new one yet this one doesn't work.
