Okay, started out i needed a level tool, have 6 guitars and like to keep them all in perfect condition, ok back to the review. After looking for quite a while, they were either poorly made, our out of this world expensive, then can across FretGuru, great price, well made and the reviews gave it dead on balls accurate, so gave it a try, NOW the older tools are in the trash.Figured if that one was so good, i'd try another tool, Dagger 2, well again he blew me away with such accuracy and design, my other fret tools hit the trash.So last but least i wanted an accurate string, fret gauge. Having such success with the Leveler and Daggar, I got the gauge, and again I'm VERY impressed.What can I say, I've replaced all my tools with FretGuru and my accuracy and overall work has greatly improved,Thanks bud, I do appreciate the hard work you put into your tooling, making my life easier..Vince Daddio
