Easy on the eye
Clean, easy to use and responsive UI, that looks good on both regular and high DPI screens.
Great extension that works exactly as described. Has been an invaluable tool in getting to know html element positioning across screen sizes.
I've been using this for a long time and works well all the time when I'm doing my WordPress theme development. Flexible and efficient for resizing my window.
This is a must-have Chrome extension. I use this all the time, and don't know what I would do without it. Many thanks to the dev!
Perfecto! Use this all the time to reliably screenshot the same width browser, depending on client, for photoshop retouching.
