The mutant V2 kits is a good system for quick change of the hotend, or tools that you will use on your 3D printer…. But it is not a device for newbees… a newbee can easy change a hotend without any knowledge of the 3D printing, only loosen a few screws, replace part, screw the screws back on and ready... with the mutant there is a bit more to do, you also have to adjust your firmware because your printing dimension changes and also your position of your print head.... this is not for everyone .... but if it is, it is a very nice device where the possibilities are unlimited
