Pros:

• Wireless, easy install
• Nice design, LED light to display the goal achievement

Cons:

• You have to wait till Sep, 2018 to get the product (and you know Indiegogo, it's not guaranteed working as advertised)
• People who live in units or apartments cannot use the product because meters are placed in common area (risk to be stolen), and maybe far from home (wifi connection wouldn't reach)
