Query: works like a charm

purchased this product after spending years fighting with my pegs and ignoring the impulse to tune at times due to the fear of breaking the strings overly often. thanks to these drops, the pegs on my violin now are working better, which means that I can turn them with ease and they are more apt to stay in place when they are meant to.Yeah! If I may just suggest that you still might need to change the strings while using this product, because I found that sometimes in the process of removing the peg to use the product, the string did not go back on so well or at times were warped even if not broken. enjoy!
