Methodology

The rule behind everything

We never invent data. If a fact is missing, the page says "Data unavailable". Every number on Lasto is traceable to a real source. We believe trust matters more than coverage: 20 well-documented models are worth more than 100 doubtful ones.

Data sources

• Official recalls: US CPSC and UK OPSS recall databases, linked at the source.
• Repairability: public EU/French repairability index publications, and iFixit (CC-licensed, with attribution).
• User failure reports: submitted by owners on this site. Reports with an appliance label photo are marked verified; public stats distinguish verified reports from unverified ones.
• Community facts: failure facts aggregated from public forums are rephrased in our own words and linked to their source — we never copy review text.

Reliability scores

No reliability score is currently published: we do not yet have enough user reports for any model, and we refuse to fabricate one. When scores launch, every score will display:

• Algorithm version (e.g. v1.0) — each version is documented on this page before use.
• Confidence level (low / medium / high) based on report volume and quality.
• A reason whenever confidence is below high — e.g. "Not enough user reports yet".

Editorial line

Facts only. "23 failures reported, median age 4.1 years" — never editorial judgment about a brand. Manufacturers can respond to any data point via our right of reply.
