I have been dying to get a go plus for the longest time and I saw this auto catch device(was debating on getting the orginal) and didn't get it till today because it was crazy expensive. After using it for a couple weeks now I decide to give my thoughts on it.
The difference between the original and this is the fact that you can recharge it which is more convenient.
1. Dust increases super fast.
2. Battery life on the phone without having the need to open the game is so much better.
3. Spin and catch without needing to look at the phone.
Highly recommended if you play pogo on the regular
