I bought a Canyon CN-GPS1, wrist-GPS. €139. It has no maps and is intended as cycle/walking/training aid with some navigation possibilities & can work as a GPS for a laptop when connected by cable.
Tried it for a week & returned it, getting a full refund. It was not accurate, slow to get a lock and hung frequently, especially when buttons pushed: Avoid.
General advice for road GPS buyers: they're only as good as the maps & Irish digital maps vary in quality. One I have does not have estates built 5 years ago in Dublin, even though the maps are for 2006. Same one found a 'bermuda triangle' in Mayo.
