An excellent product
by Colonel Dave Nuss from Colorado Springs CO USA 

Pros: Quality, ease of use, instruction manual

Nice and compact
by Greg from Scottsdale AZ USA 

Pros: Size and functionality
Cons: Lettering / markings are wearing off
Review: Compact, easy to use. Some of the markings have worn off already and I have only used it for 3 weeks. Hopefully this does not get much worse.
