cute works ok doesn t get too warm no directions [SEP] this eye massage thing doesn t come with any directions now it s not rocket science but i would like to know if there s supposed to be heat in each function if it supposed to pulse on the blue and the red light etc i say this because i think there s only heat when the red light is on the rest seem to have no heat and it is very light very slight heat as it is it makes me question is there even heat or has my face heated the crystal up so i was really expecting it to have much more heat also with both the red and the blue light it s not a constant vibration it s kind of like a pulse vibration it goes on and it goes off then it goes on and it goes offi do like that you can use it without the red or the blue light because the third setting is just a vibration and that one is a constant vibration but again that setting seems to have no heat at allthe crystal does seem to be some kind of quartz it is a clear type of crystal so i assume it s quartz because quartz is pretty commonit feels pretty nice around my eyes and if you hold it a certain way the red and or or blue light will not get into your eye you won t see it while you use it and i do like that so this is ok and it looks just like a tube of lipstick
