Review (3/5): these are more of a gag gift than a real good comb. From what I can tell
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 aren't 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're unlikely to be able to use it as a comb.
I would recommend these for a fun gift or maybe as a prop, but if you're looking for a comb to use in your hair regularly, I'd suggest looking elsewhere.
