Grades and scores
Each product gets a letter grade and a score out of 10. These are a subjective summary of the points above, written to help you compare the options on one page. They are not lab measurements, and different buyers may weigh the same facts differently.
Testing
Unless a guide says otherwise, we have not tested the products ourselves. We rank them on the information listed above and link to the seller so you can check the details before you buy.
Commercial relationships
Some brands pay us a commission when readers buy through our links. This can influence which products we feature and their position on the page. See our affiliate disclosure.
Corrections
