I have not had the chance to use this item more than just once, and i can not explain if that is due to the fact that it work so well or i used too much but the pegs are perfectly snug now, requiring minimal adjustments now for tuning. Simple to use and well worth the purchase. I have nothing but positive things to say about Pirastro products as ive used their strings and string cleaner before. Good product, small like chap stick tube, so fits perfectly in any instrument bag and has been a permanent member in mine since buying it.
