I have been using extensions for many years and have purchased a variety of different brands, some clip-ins, tape-ins, and some halo. I have used Halo Couture, Euronext, Sassina, Cashmere, Milk and Blush, etc. I always need my stylist to pop a few highlights or lowlights in them as they are not always a perfect match (which really is not an issue). This brand was EXTREMELY close to my color - which never happens - I am impressed! The past few years I have been buying the halo type. I usually have to buy and sew my own clips in, but I never really thought much about it. There are 2 things I love about these extensions, besides the color match and quality of the hair. First, the halo band that goes around the top of your head is stretchy and a little bit thicker than the ones I have previously had. It seems to actually grip, its not like the usual "fish line" type of band that can slide very easily. Second, there are 2 clips strategically placed on the weft if you want to use them. They are smaller than what I normally buy and I really like them. This thing stays in place!!! OK, so there IS a third thing - THE PRICE - very reasonable and affordable, in fact I am ordering a second set to be able to swap when I want to. Longevity? I am not sure yet because I have not had them that long (a month), however, due to the quality of the hair, compared to what I have used in the past, and proper care, I do not foresee any problems with this brand lasting for quite some time. Total thumbs-up for LaaVoo halo hair extensions!
