Trust me, you will not want to spend that little on a luka wig..The rule of thumb, is that you get what you pay for. Cheap price usually means cheap quality. And for a long wig, top quality is the number one thing you want next to the color. I can almost guarentee that wig you linked will tangle. Most long wigs do, but seeing as how cheap that one is, there's a very good chance it will. I understand you don't want to pay more, but all you are doing by going cheap is wasting money.
