As always excellent service from Lifesystems. Really loud whistle and well made. Thankfully I have not had to use it in an emergency but my dog loves it when he goes over the brow of a hill and out of sight.

I have purchased one of these whistles as an emergency sound when my dog chooses to run further than I would like him to. One longish pip on this whistle and he comes straight back! perfect. Thank you... to my dog trainer for introducing it to me.

A very loud whistle which can be heard over a considerable distance. Also it is very durable.
