I purchased lenovo Z5070 laptop 3years ago and was the biggest mistake spent so much to this product.Features are somewhat good like RAM , core i5, hard disk memory but the battery back up is very poor.Battery drains very fast its like I always need to plug in the charger maximum times.I was and I am dissapointed because in the same price I was getting other company laptops but choosen this product.I recommend not to buy atleast this Z5070 products even other products like lenovo android phones same issue I have seen.So just Be carefull! Thanks!
