The customer service was always very quick, the quality and colour is good but the thickness is not there. I ordered a quad set expecting them to be too thick if anything but they were simply thin. I have had other double weft extensions before that were thicker but they just were not very good quality I ordered these in good faith. When i emailed them with lictures of the extensions in clearly showing they were too thin they told me about the weight stated on the website. Granted i didnt even look at the weight on the website but ordering a quad set - that should be enough to prove that the hair would be thick I did not want my money back, just some more hair which they refused I am now left £125 down If you have fine hair then go ahead and purchase them but if you are like me with thick hair then unless you order two pairs it will not work for you Very dissapointed :(
