A family member in the US sent me a link to this

I found it an interesting read. My DS is 5 and non-verbal, so I was particularly interested in the GPS tracking device aspect of these products. At the mpment he wears an engraved tag when he is out and about, but as he gets bigger and more able to get away from me, I thought a GPS tracker would be a good idea. Anyone used any of these and any recommendations for products here in the UK?
