Title: Change User Hard To See
Review: I found it difficult to change to new user. With my wife and I using this unit we found it hard to change settings. The main difficulty is reading and understanding the setting buttons. You need to bring the unit close to you in order to view and change the buttons. Cannot not see while standing over it, and letters on buttons too small for my eyes. The display number is very large and readable however. Also, be sure you have paper and pencil in hand if you want to log in your numbers to compare with earlier readings.
Is the review positive or negative?
