I am using lenovo ideapad 100-15IBY . My experience with this product is not good . I am using it from 6-7 month but in these month I have send my laptop to lenovo care for two times and one time they change my speaker also and interesting part is I don’t use it any havy work just I use it for listing music and watch videos. so according to me The speaker of this laptop is not good . The other part of this laptop is good. I can use my laptop 2-3 hour if I have full charge. The hard disk is 500 gb which is also good . style and screen size is also good .
