It is very easy to use and understand, there are pre-loaded standard site images that you can drag and drop to your wireframe. Review collected by and hosted on G2.com.

I would like more export/share options. I with there were also more elements that you were able to add to the frame. Review collected by and hosted on G2.com.

I like the speed and ease of the User interface and the ready-made library objects. Just drag and drop the user interface object you need on the canvas, resize it and you're done. Review collected by and hosted on G2.com.

I'd like to export the generated files in multiple graphic file formats Review collected by and hosted on G2.com.

Extremely intuitive and easy to use for the beginner. I needed to quickly mock-up some UI flows for a website our team was constructing and Mockingbird was recommended to me by a friend. I was able to be up and running in 5 minutes with a free account, with very extensive features and able to complete wire-frame mock-ups for the flow very quickly with their drag and drop system. Their system also makes it very easy to export the wire-frame files you create as PNG's for use in an explanatory Powerpoint presentation. Review collected by and hosted on G2.com.

When you re-log in to the system, it is a bit difficult to find where your previous work is the first time (because their upper toolbar is inconspicuous). Review collected by and hosted on G2.com.

It was so easy to get started -- just 'click' on their website and I was on. Very easy to use and intuitive -- drag and drop widgets, group, etc., and share. It's possible to mock and then link up multiple pages. I esp like the fact that it is web-based and immediately went to the layout page with drag and drop funcationality Review collected by and hosted on G2.com.

Can export as pdf or png but not as many file formats as I'd like (at least in the free version). Review collected by and hosted on G2.com.

As a person who is terrible at making good UI's, I am able to use this tool to mock up what I am envisioning, and have it worked on by others to be refined, and made functional. Review collected by and hosted on G2.com.

Lack of formats for exporting, it means while using the free version, you are very limited. Review collected by and hosted on G2.com.
