I have now owned 2 I40's. The first one I owned for just over 5 days and had to send it back to have warranty work done. They sent me a new one because the LCD display was not working. I just put my new one out yesterday so I will see how well it works. If I continue to have problems and have to keep shipping it back to them i'll be asking for a refund and getting a cuddeback. Cross my fingers!
