these are more of a gag gift than a real good comb from what i can tell [SEP] these combs were purchased for my son according to him these are more of a gag gift than a real good comb from what i can tell they are fairly well made but the materials are not extra high quality the push button and eject work mostly without incident occasionally getting stuck but not regularly the comb portion itself is very shallow so if you have thick hair you are unlikely to be able to use it as a combi would recommend these for a fun gift or maybe as a prop but if you are looking for a comb to use in your hair regularly i would suggest looking elsewhere
