Review (5/5): I'll wait and see...  I waited and I'm amazed
I may upgrade the star rating on this later. I had expected this comb to be a bit more substantial than it is; but since it is made of carbon fiber, I'm willing to be convinced that it's better than my first impression. I have very long hair that tends to tangle badly, and so far it's held up, but the teeth are sharp, don't like that much.
Update on this review. It's now months later and the comb has still held up well and I've gotten used to the sharpness of the teeth. Today the most AMAZING thing happened. I went to pick up the mail after it was delivered and there was a small package. I didn't remember oredering anthing recently. When I opened it, it was another comb from this company, along with a note saying they noticed my somewhat negative review (3 stars) and wanted "to make it up to me" and sent me another comb, free of charge. People, you can't find customer service like that anymore. I'm completely impressed. Also let me add that I have waist length hair and usually go thru combs at least once a month or 6 weeks. The original comb is still going strong. Perhaps I'll give the new comb away to a friend to drum up new business for this amazing company.
