Pro Single connection to your device
There isn't any Wi-Fi in this product to set up, meaning the setup process will be as easy as pairing a new Bluetooth speaker. Also, even while you are having internet troubles this switch will still work with your phone. Some users have even plugged their Wi-Fi router into this, turning it off when they are at work and sleeping.
Con Bluetooth limits the range and situations in which the device can be used
Bluetooth has an effective range of about 20 feet, depending on variables. You won't be able to adjust this switch through the internet like you will with most of the other switches available today. If you left the lights on after you left for a vacation, you'll be much too far to turn them off.
