so so [SEP] i am a nail tech and in school was taught to not shake the bottles but to roll the bottle before using but thought i would give this a try it is kinda noisy but really do not see anyway around it so i am not going to hold it against them the machine seems to shake itself more than it does the polish i have found putting a towel under it keeps it from shaking off the table and helps with the noise a little i have tried regular nail polish and gel polish in this machine and would say that it did just ok with both all in all i would say save your money this machine is not really a time saver
