These wipes can be perhaps a good "on-the-fly" option to have in you gigbag, a.k.a. for a last minute instrument clean-up. That said, I did not find the string cleaner to do much if I am honest (granted, I used nanocoated strings so these wipes may not work that well). The string cleaner component seems to be quite nasty and not sure I will use it again as the instructions tell you to wash your hands after application... Don´t they know that strings touches your hands?
Also, I would have preferred one extra pack of fretboard conditioner instead of 1 and the 3 packs of string cleaner. Could be 2 and 2.
My two cents: For the price, okay I guess. But for instrument cleaning at home, I would go for other options. For gigging: perhaps, but I would rather use a good microfiber cloth if I am honest.
