This is a pretty handy all-in-one kit, but the product itself isn't great. As others noted, the bottle for the lemon fretboard oil is defective and doesn't really keep a tight seal. Fortunately, I was able to transfer the liquid to another spare from a travel shampoo bottle. Also, the cleaning cloth is great for guitar bodies but not fretboards. The fret edges will cause the cloth to fray a bit, which leaves small bits of fabric on the fretboard and the cloth with a visible "torn" look in the area used to polish the fretboard. I use the cloth just for body polish, and something else for the fretboard though.
