Really good quality clip-in hair extensions?

I bought some Donna Bella hair extensions last Christmas and they were absolute crap. They were thin and the hair fell out. Now I was going to buy some more, but I wanted a better brand. I was going to get Hello Gorgeous because they seemed like such great quality, but there are countless amounts of people that have waited for over 4 months to get theirs, and I'm not sure if I want to waste money to never get them.
