Review title is Blah results. I didn't see/feel any difference. [SEP] I have been professionally trained to file nails. I have a license and degree in Cosmetology but I don't practice professionally. Nail filing is a skill anyone with a file can master. I bought this because I saw it was recommended for use with jamberries. I have some but I was interested in using it with my super thin sensationail nail shields. It's a thin flimsy sticker you can put on before applying gel polish which makes the removal much easier. I'd compare it to a super thin jamberries.<br />Unfortunately it didn't help as expected. I am painting my nails right now and was using the stock mini disposable file that came with the shields.<br />I found this file feels a little dull. I can't see any difference in using this or any regular file.<br />The nail stickers still have a raggedy edge and it didn't feel any smoother than when I use other files.<br />I am not interested in trying another brand/style at this time due to the blah results. It's not a must have for the arsenal.<br />I'm giving it an extra star because it is constructed nicely and I haven't broke it, which says a lot about its durability.<br />I can't handle rough nail edges it makes me cringe. I'm using it while I write this review and it's just confirming I don't need this.
