I got one of the first batch of Motion Loggers to arrive in the country. Have over 50 sessions logged by it... NOT ONE ISSUE. (Except when I forgot to turn it off until I got home.

) Only 1-2min to download to phone, export file to KA72, then on to GPSTC.
Charge it for 2hrs after about 10hrs of use (2-3 sessions).
As one of the original GPSTC participants (2007) and having had- a Garmin Foretrex 101, GT-11, couple of GT-31s, Canmore and GW60, I believe the Motion Logger is the easiest to use, most reliable, most accurate and best value for money, rule-abiding device that I have used. Cannot fault it... I just use a Garmin watch for on water feedback of how slow I am compared to my mates. Fully recommend it.
...and no, not a paid advertisement.
