With 785 write-ups covering 3,224 products, some of it will be out of date at any given moment. Corrections from readers are how that gets fixed.

[email protected] is the only way in, and it is read daily.

• Corrections — a wrong figure, a dead product, a claim we should not have made. Handled first.
• Suggestions — something we have not covered.
• Commercial and legal — licensing, reuse, press.

Every message is read. Not every message gets an answer — corrections do.

What we cannot help with

Please do not send order numbers — we have no way to use them. Amazon handles delivery, returns and refunds. The manufacturer handles defects, warranty and documentation. We are neither.
