Pokemon GO Plus

Pokemon Go Plus helps you catch them all without getting hit by a bus :)

Pokemon Go was a very playable mobile game, last year.

Pokemon Go Plus is a portable gadget that allows you to catch Pokemon and objects just with a push of a button without looking at the phone.

Connects to your Android or iOS phone via Bluetooth.
It's has LED notifications:
-Yellow: you're near a Pokemon you have never caught
-Green: you're near one you have caught
-Blue: you're near a PokeStop.
-Red: you're out of range
-White: your bag is full
-multiple-colors: items have been added to your bag

You can clip it on clothing, or attach on your wrist.

It comes with a CR2032 cell watch battery.

Pros: Great to hatch eggs and catch Pokemons, affordable: only $34.99; easy to connect, simple to use.

Cons: Hard to see the LED outside, disconnects randomly from Android.
