is that it doesn't log the distance you've done on each bike

+ upload/download to PC for analysis, not explored the usefulness of this yet, but you can see stuff like on that 3 hour ride you felt fine for the first 2 hours then bonked, infact you'd been tailing off from 90min in so next time you know the signs to look out for before you bonk.
– not very accurate, its lucky to position you within 150ft unless your out on a moor or somewhere equaly un tree covered. I've a 20yr old magellen GPS, about the size and weight of a house brick but fixes much more accurately.
– as part of the above, the speed it shows is pointless off road, especialy on really tight singletrack you can go round a few corners before it picks up the next signal and registers that you've moved.
-buttons get clogged with grit, but its easy to wash out
-speed/cadence sensor is another £40
-it would be cheeper to buy speed/cadence computers for all my bikes and a HRM.
I'd buy another if it broke, but for 90% of my riding (Swinley) its fairly pointless, on the road or on big epic rides in the Peaks, moors etc I imagine its prefect as most of my gripes are with its use with MTB's on singletrack.
