Should I get a laptop with good specs from asus or a slightly better laptop from Sanger both same price but no review for the sanger one?

I'm with letmepicyou. I have never before heard of Sanger until your question came along. So who knows if they make good computers, how good their customer support is, etc. I would personally stick with Asus since they have a better reputation and are more well known.

My first instinctual reaction is, "Who the h*ll is Sanger?". That's usually a good enough reason to avoid a given product.
