I'll second that.
I have sailed many thousands of miles with a 72 and before that a 76 (same thing) and only on my very first unit back in probably 1999 one of the buttons broke off which was then a known problem (rubber membrane was too thin) and subsequently modified. My unit was replaced with a new one no questions asked.
Since then I have added two 72 units for redundancy, one is 3 years old and still in it's factory packaging. They never seem to give any problems. But to be fair, mine have an easy life. They only get switched on twice a day when I want to update my position on the paper chart (sorry I still use those
). The rest of the time they're cozy in the chart table.
