An excellent product

  • By Colonel Dave Nuss from Colorado Springs CO USA on Monday, January 19, 2015
  • Pros: Quality, ease of use, instruction manual
  • Review: APR make, by far, the best E6-B computers. Bought this as a Christmas present for a friend in South Africa who admired mine. Spend the extra money and buy the most expensive model...you will have it as an heirloom to pass on...well worth the minimal extra cost Instruction manual is superb.

Nice and compact

  • By Greg from Scottsdale AZ USA on Monday, May 24, 2010
  • Pros: Size and functionality
  • 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.
