I purchased this unit and was amazed and it capability and multiple functions. It was, for me, difficult to read due to it's small size. Otherwise, overall this is a fantastic unit that can cover the bases for most everything that a cyclist might want to measure while even connecting with your phone for calls and messaging. I did however, return it and tried the Macro GPS which is much easier to read.
I wanted a smaller cycling computer and the Lezyne delivers. Small , compact and for the size the font is not bad. Im in the 50 plus club so if you wear reading glasses you may want to with a larger model.
