I bought a Guitar for my daughter a couple weeks ago through internet. Neither I nor my daughter had any idea about the tuning system. When she went to get her lessons it was found that one of the strings does not create any sound, and the guitar is useless. I had to buy another guitar for my daughter from a musical store, so the money I spent for the first guitar was wastage of money nothing else, and I had to garbage the guitar!

So my suggestion to people who want to buy any musical instruments they should to go to a physical store and by from there.
