I was hesitant to buy it after reading so many bad reviews but as I could return it if it was not working as it should I did order it.First push of the power button, nothing happened. Read the accompanying paper that you have to plug it in.Doing that it worked immediately. My guess is that they put it in a deep power down not to deplete the battery while on the shelf waiting shipping.I tried every accessory ports including external monitor, micro SD card (read and write), Bluetooth (4.0 BLE), etc. Everything working as it should. Battery charged quickly and after a few hours running fromthe battery it was still more than 80%. It also looks like new and was well packed.It is very fast and going from my 15.6" Lenovo was not as bad as I thought it would be, maybe because it is way faster than my Lenovo.Until now I am happy and I hope it will continue to work for a long time.
