Euronext sally's extension opinion?

Well im 16 and for my 17th birthday i asked for clip-in extensions and my parents are going to get me some. I havent really had experience with extensions so i researched a bit and i saw euronext remy human hair kind from sally's beauty supply and they seem pretty good from the reviews i've read and such but im not positive. if i do get them im planning on getting 18' jet black ones. anyone have any suggestions?
