Corrections, questions, and product suggestions.
The fastest way to reach us is email.
Corrections are the most useful thing you can send. Prices move, products are discontinued, and a guide that has drifted out of date is worse than no guide at all. If you think we have misread a piece of testing, say so — every claim on this site names its source precisely so that you can check it.
Product suggestions are welcome. Tell us what you are trying to buy and what makes it hard to choose — that second part is what turns into a guide.
PR and samples: please do not send products. We do not test them, so a sample tells us nothing we can use, and accepting one would compromise a method whose whole value is that it is independent of you. Send us your published test data instead — that we will read.
