If mine broke I’d buy another straight away. ‘Tis true that it won’t give you an OS grid ref, but to be honest I’ve never missed the ability since I stopped using an older eTrex previously.
Mine works fine everywhere but city centres surrounded by tall buildings; I’ve never had a problem with signal loss or poor accuracy (including over a thousand miles around the Malverns too).
For recording rides, using as a souped-up bike computer and following courses made on computer it’s great. I love the fact that it unobtrusively sits on the stem; are there any GPS units smaller than the 205 and 305?
Since I got mine 3 years ago I think I’ve broken 3 mounts; one while carrying the bike on a car rack and two in crashes. They don’t cost much and are easy to replace, so I’m not fussed. I’d rather the mount broke than the GPS.
