An absolute must for frequent Griller

An adapter hose with pressure reducer makes sense when you stationary, want to use permanently Grill on the balcony for example, and want to operate only for Picnic by small gas cartridge.
This therefore makes sense, since a 5 KG propane bottle even cheaper (4-6) is, as a small Weber cartridge (approx 7-8).

Note from our own experience: When hard-start thread, there is a reason for complaint. I have complained about this, and a new grill get where the thread is to operate by hand and without tools.
