Mixed review. It didn't have the internal battery, instead it had a weighted plate in its place.... I got this thing really cheap so its hard to complain, but atleast leave the internal battery section empty, damn. Besides that, it's in real good condition. The external battery also passed the lenovo vantage test, so that's good, but I bought an extra external so I could hot swap batteries without the charger plugged in, now I have to go buy an internal battery. Overall I'd still recommend it if you can buy one cheap, mine was $200.
