Honestly, future landfill unless the battery cells can be serviced or replaced.

If you need one for emergencies, sure. If you need a UPS, get a UPS instead.

All devices are gonna end up in a landfill eventually. LifePO4 should last much longer though.
The battery technology is solid, LiFePO4 cells should be good for 10-15 years if they’re not abused, but my experience with these things is that the electronics are cheap and will fail long before the battery does.
