I had ordered two pairs of the diane 7111 models (the combs) and like them so far. I bought two of these combs just to use one for now and save the other one in case if the first one that Im using now gets lost. Diane 7111 model is a great comb to use. I like that its sturdy too without it becoming bent or fragile from frequent usage. I noticed that this type of comb is only recommended for people with smoother and finer hair, but my hair is actually very thick and coarse and the comb still works well with the type of hair that I have.
