I'm sick of coaching you uncalibrated monitor PEOPLE!

Yeah, get on this one. I use the same one and it's made a giant difference for me. You can do multiple monitors and everything.

Made a huge difference for me too! this is SUPER cheap! Get on it!

$100 off!??! It pays to know Hurley.

I would never have realized just how bright I used to keep my monitors without starting to use a calibrator. The people who see my photos seldom have calibrated monitors, but at least they now see mine the way they see every other well calibrated image.

One of the best purchases i have ever made.

If you don't start with a calibrated monitor you will not learn to see color properly. Unless you can see a true gray you won't really know where you're at. It's like playing a guitar out of tune.
The other thing to do is to start using the entire system. Get the bundle with the ColorChecker. Shoot the target under every light set up you use, on every camera you use. Create custom profiles for every combination of lighting and camera you have. So now you have a custom calibration for your sensor, under your lights, with your monitor.
I'm shooting Nikon D750s. The skin tones are naturally pretty good. But when I apply the custom calibration using the entire X-rite system I see the various shades of blue pop. Certain reds are unruly without a custom calibration when I shoot to my MacBook tethered. So this is another reason I'd use the whole system. I try to remember to take that little ColorChecker case with me everywhere even on editorial stuff.

How painful is it that today I dropped mine and it's broken....Let me go cry in the corner.

I love having a calibration tool in my workflow. I did have problems getting proper colour balancing on my MacBook Air. The small medium and large patch options gave widely varying results. I emailed xrite (xrite China), and they told me I should stick to small patches. Their rationale was that large patches actually don't make the calibration more accurate (go figure... I wonder if that's their way of blowing me off...)
