You baught a cheap one, the good ones are machined so the spikes inside cant break off. Dont buy those cheap ones, cause most are made of aluminum and when they break you could be smokin aluminum shavings, that is heavely linked to alzhimers and a whole bunch of other shit. just make sure the spikes are not pressed into the mettal and were shaved out of the metal
