I was genuinely surprised with this tool kit - the bits and pieces in it are not the highest quality German-made hardware stuff, but it is usable nevertheless.
Any luthier or tinkerer on the guitar already has a better toolkit than this. So, who is this for? This is aimed at your everyday guitarist who just needs the tools to get the job done - be it string adjustment, turning some knobs, messing with floyd locking mechanisms or the STRING CUTTER. If you do not have the latter, please get it for your own sanity and... safety.
The magic cleaners that come along with the kit are... well, I wouldn't trust them to clean an expensive guitar so these are there to literally look pretty and that's about it - the ruler and gauge are very very useful and the cloth is okayish, a bit rugged and not as smooth as I like my cloth to be, but can't complain.
However, the toolkit is very nicely made and if you just need these items to tinker about your guitar and do basic maintenance, this could be the right purchase for you (Fender toolkit does seem to be better, but then again, Fender doesn't ship to a lot of Eastern European countries).
