Hi just thought i'd write a review as no one else had. thought i would give the "kyser" string cleaner a try as always used "fret fast " before, i was pleasantly suprised as to how good it is , seems to be non sticky so far, easy to apply with no fluff and waxey feel to it, also brings the fretboard up a treat, so well pleased. I would also like to add that the speed of delivery by "strings direct" is truly impressive i ordered in the afternoon and it was delivered first thing the following day, regards larry
