As far as I am aware - camelcamel graph says so anyway, this is the cheapest price that this product has been. I was in the market for one of these kinds of devices and thought that I would share because it is a good deal but ALSO because I feel strongly that everyone should have one of these in the home. If 100000 people got one to save one life it would be worth it.
Only just worth it for that one person... depends on the person tho!
