I was pleased with the build quality of these notched keys. But look at the picture and note the diameter of the black part on each end of the box: it's about the same diameter as a regular end of the box, and the GearWrench body is thick enough to often restrict where you put it can use. Since I bought them I've noticed how often fasteners are found near inside corners, pipes etc and I can tell that if you're carrying ratchet wrenches you'll need regular box wrenches as well. I work with low power engines, snowmobiles, ATVs and cars; no longer professional, but often enough. I could do without this, but I love the extra shine in my toolbox. I'm glad I got double sided ones that have an offset and others don't - the knuckles have to go somewhere. However, I don't intend to set the metric right now.
