Thanks Sarah. Can confirm its an excellent plugin, the quality of the device frames is fantastic.

I'm currently using this in conjunction with Browser Shots to pull in live website screen-shots rather than manually creating them and the two work very well together. This does fall down however when using the device sizes. Browser Shots just inserts a smaller version of the full sized site. Have discovered its actually very difficult to find an automated screen shot system for WP with responsive screen-shots. Has anyone else had any luck with this?
