The device comes with an easy to use, German instructions.
Conversion problems, if one considers the special "left-hand thread", ie: hard turning counterclockwise. When in doubt, what you are doing: let make anything from a gas / -frau or can be removed!
Conclusion:
Rd. 15 Euro savings over the original.
PS: By the way, the gas-bearing parts should be cleaned, as long as the grill is older than a season :-)
