Battery collapse just after 2-year warranty

Rechargeable battery

24 months

Source-linkedVerify source — Coolblue review

Coolblue review by Pieter (original Dutch). Just after the 2-year warranty ended, a full battery only lasts about 1 minute. Sees the same pattern in other reviews; for such an expensive product expected better lifespan.

Source-linkedVerify source — Coolblue review

Coolblue review by Jeroen (original Dutch). Called it the worst and most expensive toothbrush ever owned. Failed three times after about six months each time. Battery constantly drains; after 7 hours of charging only about 1 minute of brushing before it shuts off again.
