"Often" is not "always". I have a 92 and a 295 and a 195, all of which have had "sticky buttons" problems among other glitches. None has been deemed fixable by Garmin when I've asked. Your mileage may vary.
Well, gosh, the 295 first was sold in 2000, the 195 in 1997. 17-20 years in the electronics world is eons! As in the dark ages, dinosaurish, practically pre-Cambrian!
