Device Ratings Guide
At the top of each design page, you’ll find a series of five icons in either green, yellow, or red. The meaning of these icons is re-resented below.
Please note that these ratings are fairly subjective, and we welcome your input. If you feel any of the ratings for a particular device should be modified, please [fill out this form](https://docs.google.com/forms/d/e/1FAIpQLSdhXbiOOM0osnWC3ZsImSWuSblbbnKVcWtzMesCU_ynLmFhjg/viewform) and share your thoughts with us.
