Definitely worth every penny.
I have owned , purchased, obtained plenty of 3d printing tools, usually the kits come with one tool that almost all the focus is on, and then throws in some cheap add-ons to make it a kit. This means that i end up with many different kit from a bunch of differing sources, just to make up one decent kit. The wham Bam maintenance kit has everything you need to take apart, clean, and maintain your 3d printer without having to search for that ONE TOOL to rule them all. Very well thought out and practical and i put it use within hours of receiving it, glad i bought 2 sets.
