No batteries, but I always like mentioning these guys when this conversation come up because to me, they are the definition of BIFL. https://www.pkgrills.com.

Patented design back in the 50s. Have not changed their moulds since. 70 years later you can still call them up and order parts and they are garenteed to match.

Ya, because plenty of people still use your model Dyson. 6 years still not end of life.

That’s the point. How many third parties are going to be making that battery 6 years from now when the vac is EOL and everyone but you has upgraded. They aren’t going to make batteries just for you.

No. They don’t manufacture the consumables forever. You’ll get 10-15 years of manufacturer support. Maybe a bit more with Dyson…(?).. but it’s not life.

Even if it is “only” 15 years, it’d still say that’s pretty solid, but not BIFL.
