I've had this soda maker for quite a while, and I'm really surprised by its durability. After frequent use, none of the machine's components have shown obvious wear and tear. The gas - generating function is still strong, and the bottle hasn't deformed or cracked. Unlike some small household appliances I bought before, which frequently malfunctioned after a short period of use. This soda maker has excellent quality and I feel it can be used for many years. It's really worth every penny.
