Good idea, but...
In theory, and before it falls apart, this is a great product. Cleaning my strings and fingerboard was a breeze, and the fact the cleaner is washable justified the rather high price-point in my mind. However, the cleaner literally fell apart after maybe
two-months of use. I can't say exactly what happened, but when I picked the cleaner up from the table the spring and metal bar popped out. As I ponder the possibility of the metal pieces falling into my violin, perhaps I should consider myself fortunate that
the cleaner broke in my hand versus as I was cleaning my strings! I am really disappointed that I wasted $20 on this cleaner.
