I'm installing it now. I've seen a few videos where people have Resharper installed and it is amazing how fast they are writing code and navigating. In the past, I've had to uninstall Resharper because it was too much adjustment and too many of my keybindings were changed. Now I'm on a project where it is required.
The reality is, I have time for one good video on Resharper today. I'd like to come back and watch more videos but unfortunately I can only do one. During my normal work day, I will be exploring the code base of an existing project.
Can you recommend a video to start with that might improve my productivity today?

When you have time, watch more videos from the ReSharper channel on JetBrains TV or take a couple of hours to take an awesome ReSharper course by Pluralsight
Btw you didn't say what kind of project you're working on. If it's any kind of project that uses XAML, I'd recommend Using ReSharper for developing WP7 Applications as an overview of how ReSharper helps in WPF/WP7/Silverlight. Otherwise, "What is ReSharper" is the best pick.
