With 1,546 write-ups covering 1,417 products, some of it will be out of date at any given moment. Corrections from readers are how that gets fixed.

Email [email protected] and it will get to whoever can deal with it.

• 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.

You will hear back about a correction. For other mail we do our best and make no promises.

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.
