I have been a software engineer for the past 20 years. I developed for many types of devices, including Android. MIT AI2 Companion is just amazing! It speed up the dev process so much! It is pretty stable if you know what you do. I don't often write reviews but after reading some 1 star reviews I had to write one! It seems to me that people howadays expect too much without any knowledge whatsoever. You have here an amazing dev tool and still you complain. Stop developing if you can't handle it.

Couldnt even download it. every time i tried, it defaulted to AI2 Companion for which there was no way to open. I guess upgrading from something that used to work, isn't always better. Anyway Blynk works fine.

One thing I hate is the application not pushing through 10-20% like IT JUST GETS STUCK THERE. I need this to test my project for class.
