My house gas leaking, so I go and buy a gas regulator.
I bought the below model at RM 28 at Semenyih, Ban Hock Hin Trading beside Econsave Semenyih.
The shop is selling Butterfly gas stove/hob.
Lazada is selling at RM 49.90.
I also bought ZANUSSI hob at Lazada on 11/11/2017 after survey for 3 years.
