Once you hit the pavement with your Motion Lingo Adeo, it needs to lock on to GPS satellites. This took us more than a half hour the first time and varying amounts of time after that (from 2 to 20 minutes). It works faster in clear surroundings, but any wait is a nuisance when you're ready to run.
The interface of the device itself could also use a major overhaul. Buttons are scattered around the shell and are labeled only with unclear icons. There's no screen, unfortunately, so you need to listen to the spoken instructions. Press power, select the option for a timed workout, then push to start your routine. And be sure to hit stop when you're finished.
Depending on what mode you've chosen, audio cues will report your distance, speed, calories burned, elevation, average pace, battery status (the Adeo is rated for 6 hours), and more. When you're finished, you can connect the device to your PC and save or even upload the data to a complimentary Web account and see your route using a Google map. The Motion Lingo Adeo works only outside, so it won't do you any good if you're running on an indoor track or using a stationary cycle. The packages include a belt holder that fits your Adeo and a portable player, although we found it uncomfortable. We stuffed them both in a Marware Sportsuit armband case instead.
