High quality puller with annoying key width

This puller for FAG bottom bracket is of high quality and is working properly. FAG bottom bracket can be so off without problems within minutes and screw back. Therefore there is nothing to complain about. However, one needs to use the puller in addition a wrench or a hexagon socket wrench with wrench size 28. The size is the problem here. Although 28 is not super exotic, but not necessarily consistently. Therefore it does not belong, for example. Usually the equipment of common Schraubenschlüssel- or socket wrench sets. What's annoying. And for me it came down, that I had to additionally buy a corresponding nut. Typically, then had the first hardware store, I have scoured without wrenches or sockets available in this size. Long story short: It would have been much more useful if the puller had been made for use with wrenches of common wrench size 27. Especially since the puller is robust for more than adequate.
