Has anyone used Lens Align?

I am wondering if anyone here has used this product?

LensAlign® Focus Calibration System

If so, is it worth it or sending a suspect lens back to Canon is preferable...

I haven't used it, if there are any types of vignetting, aberration, geometric distortion or whatever else in the picture, Adobe Lightroom has profiles for a lot of different lens, that automatically fixes those things for you.

I am looking at this device in regards to front/back focusing.

It's the best product of it's type on the market today, if your camera has the fine focus adjustments that can take advantage of it.

Luminous landscape has a review they did a couple of years ago.
