the rose quartz roller is nice [SEP] the rose quartz roller that comes with this is really nice and i use it all the time the micro needling kit not so much i am assuming that these are supposed to be one use and disposable as there are no options for changing replacing the needle heads which could be a good thing in that at least you know for a fact it is clean i read a lot about this and generally feel that it should be left to professionals there is no way to tell what shape the little needles are on this which from reading is pretty important and there are lots of things that can go wrong i am all about doing stuff at home but i personally do not think a disposable micro needling kit is one of those things
