UK decision boundary

The cheaper option needs about 5.5 years of average life to match the premium’s purchase-cost pace over six years.

This is an economic boundary, not a durability prediction. A full second LUBA 3 AWD 1500 purchase would take spend to £3,998, £1,799 above one Navimow X420. The premium must still earn about £33.33/year through less hassle, lower downtime, stronger task fit, service or residual value.

How a UK buyer should read this

1. Job fit comes before price.

Reject an option that cannot cover your lawn size, slope, access or boundary conditions. Cheap but incapable is not value.

2. The premium needs a job.

More money should buy something you use: fewer rescues, better terrain capability, lower downtime, easier setup, stronger UK support or a longer useful life.

3. Unknown is priced by consequence.

If mower downtime is tolerable and replacement is easy, a newer or less proven model can be a rational gamble. If service disruption is expensive, pay more attention to mature evidence and UK support.

4. Re-run after a sale.

Useworthy does not freeze a permanent winner. A real UK sale can flip the transaction.

Is the break-even lifespan a reliability forecast?

No. It is a purchase-cost boundary. Useworthy does not claim a product will actually last that long.
