So having the spare parts is just for feel yourself safe.Because believe me you don't need that parts maybe for 2 years.The atomizer gt4 is very well made the parts are extremely good.The only thing I can say if you loose some parts than yes you need them so that is why I get them.

This is handy just because you may need to rebuild your atty after lots of use or you could need just one of the insulators or something

A must have for Taifun GT IV owners. Don’t be caught with a leaky tank.
