How long does a SWFT mod last?

Could you please elaborate on the lifespan of a SWFT mod? I'm particularly interested in understanding the factors that might impact its durability and how long users can typically expect it to function optimally. Are there any maintenance tips or precautions that can be taken to extend its lifespan? Additionally, is there a general warranty period or guarantee associated with SWFT mods, and how does this compare to similar products in the market?
