I have been using this light and understand why it always gets such good reviews.

Astonishing DEFINITIONS, what more needs to be said!

A perfect tool to check swirl marks. Easy to carry with you at all times. Convenient to use. I'm glad I made this purchase.

I purchased this and the Rupes pen light to do a side by side comparison. The scangrip has just a tad less lumens but it is an effective swirl and defect finder. The quality of the pen light is excellent. It's comfortable and it's easy to turn it on by pressing the button on the back of it. It is not heavy and the portability of it is nice.

The adjustable focus on the front allows the lights intensity to be adjusted and works well.

The light color is that of daylight to give a true color of the paint. The 4000K temperature of the light is nice compared to other swirl finder lights that can be in the 5000K range. This one is a little easier on the eyes.

Overall this is a great pen light and makes a great alternate to the Rupes light during a Detailed Image sale. It is an effective swirl and defect finder.
