I was used to purchasing extensions for around $100 a set (I was purchasing proextensions)so I decided to give this cheaper option a try back in August of 2011. They were the SAME quality as the expensive ones and it's now 8 months later and they're still in great shape. I have fine hair so one set of these is perfect for me. However, if you have thick hair you will definitely need to order more than one set (my friend had to order 3 sets for her thick hair- still only around $150, which is WAY cheaper than other brands). Also, I would not recommend shampooing extensions. I only use conditioner and let them air dry. I shampooed my last set of extensions and they dried out and were VERY difficult to get back to the original condition.
