I once bought a wig from wigs.com, and the quality of the wig was quite good. I kept it for about 2 years. So when I needed to have hair extensions, I still chose this store.
Of course, these 8 pieces clip in remy human hair extensions are of high quality, just like my natural hair. Besides, their delivery also satisfies me a lot. I placed the order on Wednesday and got the hair on Friday. I have no idea how long they will last. But referring to my last wig, I think they will also be long lasting.
Since the extensions on this store cost much more than those in other on line shops, my opinion is just for reference.
