I work in the Energy Industry, operational repair personnel at the Energy Facility. Repair and maintenance at electrical installations. For 33 years of experience, I went through a bunch of tools, but WERA is something. Working for them is a pleasure. Especially in SCHSN and other places with difficult access. For the repair and maintenance of internal combustion engines, it also often helps out. I replaced several heads in the kit with more necessary and more commonly used ones. In cooperation with other sets and tools from WERA, they combine elegantly and complement each other.
