This has to be the coolest tool kit out there. VERY hard (and even more expensive) to find. Incredibly light and strong. Impervious to weather, corrosive environments and sea water. Entire set weighs only 3lb. 4 Oz.
There are pretenders, but this is the REAL IMPREX - made specifically for GE to service their MRI machines. If you're here you know what you're looking for. It doesn't get any better than this.
