nicer looking in person drill bits in case attached under drill files pop off sometimes [SEP] i got this to be able to do my nails from homepros the reddish brown filing pieces that attach to one of the bits has pieces but they are flimsy they do not look like they will last very long and they are thin the dial can be adjusted but there are no numbers or levels you just move it around until you think you have the speed you want i do not like that because if you know a certain level you are comfortable with you to have to make your own markings with a sharpie or something because it is kinda hard to remember where you had it for a certain nail real vs acyclic or for certain drill bits minus half a star there is no click when putting the drill bits in so you just have to push it in as far as you can however i did this and sometimes it would fall off so i had to push it in as far as i could minus half a star conclussion i got this product free in exchange for my honest and unbiased review
