How to know a laptop is good for me?

I chose a Lenovo, the specifications meet my needs, but I'm not sure about buying it. How do I know it's a good laptop?

Well Lenovo(I'm Also Using) Is Good Laptop, But You Need To Check The Online Reviews Of That Model You Going To Purchase If You Tell Me The Specification And Model Then I Will Tell You Howz The Laptop. Good Or Not.

It's Lenovo. You can be sure it's good for you.
