69 euro for a button is ridicules which is even more crazy when it's for only 2 years subscription (wtf it's a freaking button), even flic (https://flic.io/) is 34$ and doesn't require a subscription.
But I am also non-plussed by this offering. Ignoring the price, this should come with an option where it isn't dependent on external servers. For me, Particle's Internet Button[0] is still my favorite solution on the market.
