It works quite well for us. But you have to be aware that GPS only works outdoors. If you are indoors, the receiver usually receives no signal from the satellites. The position is then calculated approximately on the basis of previous data, if this is available. In addition, the receiver on the Explora is not the best. It's not as precise as you might be used to from a smartphone and I've also noticed that it doesn't always receive the signal when tracking, even when the watch is outdoors. I just don't think there's more to it for the price.
