    With battery life that bad, I’m surprised that it does not come with a wall wart adapter add on.

    I own a first generation 189 (purchaced new) and I was worried about the short battery life when I got it, but after 3 years I can say it isn’t that bad.
    I takes about a year to show BAT on display.
    I admit tho, I don’t use it daily…

    What really disapointed me was the (7 seg) LCD. Not all segments have the same contrast and some are so fade that I have to look at 90 degrees angle. Awfull viewing angle.

    I wonder if I got a faulty one?

      Yes. Its’s faulty. Problems with the rubber contacts to the LCD. You could repair it by yourself.

    Hi Dave, great brief review/comparison video blog!

    I feel that two products compared belong in a different class and are aimed at different users with different priorities.

    A comparison of the 87 and 177 might have been more appropriate.
