This kit from Cruztools is great. All the tools needed for a basic guitar setup is included and of good quality. I've been using this when I've been setting up both my guitars and the result is great.
What I like with this product is the way it all comes in a bag that easily fits in your guitar case, and will help me adjust my own guitar. With the included guide you can learn the steps and measurements for different guitars, helping the guitar player learn how the guitar set-up is done.
The only thing I don't quite like is that the skrewdriver don't have a magnet that hold the bits. I would like to have the ability to switch to any bit, so that I would be able to use the skrewdriver anywhere.
