Simplicity and portability.

Finding the simplicity of operation through the menu system. That's very complete. A great aspect of this piece of equipment. Portability is incredible. I work on law enforcement, fire department, communications equipment and vehicles and different kinds of apparatus and all kinds of different train situations and locations. This is perfect for me. Really looking forward to it. Have used it in some functions so far and it's been flawless. No complaints. I love the exterior case with the rubber bumpers great for in the Field use. This product. Was thought out when it went through research and development. Thank you for making my job easier. Looking forward to testing more of your equipment that you have available.

Second Try

Please ignore my first review. I did not see that there was a screen protection sheet on. That had the scratches. Apologies.

Pros: size of unit, fits almost any kit.
Size of screen and layout. Information is very visible, and two color schemes.
Accessories: multimeter leads, alligator clips, o-scope leads, and a USB cable.
Built in kick stand.
Contect sensitive guide to connections

Cost-very good feature set for a modest investment.

Cons. None so far.
