Edit: Nevermind. Wrong one.
It is a good deal considering how many items you get for that price.
That’s just over $15 each for the items.
Door and window sensors for that price is excellent, as is the motion sensor. Those small plug style sockets are typically expensive. The SmartThings branded one is over $50.
The button could be a good deal if you have a use for it. Otherwise, it might be a little underwhelming since it’s only 1 button and a minimote could do more for $20.
The $99.99 pack is a good deal since it drops it to $60 before tax for a motion sensor, 2 door sensors, and a keypad.
