Suunto watches are superb; I have had a first generation Suunto Vector for over a decade and a T6c for 18 months. Both are reliable, accurate, easy to use and I wouldn't swap either of them.
Unfortunately the same cannot be said of the Suunto GPS POD. I gave it half a dozen outtings, but had to conclude that it simply cannot hold a signal once you're on the move. In town or out on the South Downs, under tree cover or wide open horizons, it's made no difference; can't get the thing to work properly for more than about half a mile. That renders it worthless as a training device. It also munches batteries like nothing else. Could just be bad luck, of course, but it seems others have had similar experiences with this product.
For running, get a Suunto Foot POD instead: accurate, current speed in real-time, batteries last for dozens of training sessions. Personally, I much prefer them over GPS devices - even the ones that actually work!
