I've been using ion channel for over 2 years now, not only is it highly effective but they have great customer service as well! They are always willing to help you out if ever there's an issue or question that needs answering- which in my experience rarely happens with any software/platforms nowadays (I'm looking at ui designers).
The platform works seamlessly across all devices allowing me access from anywhere while providing accurate data when needed most - no more guessing about what people look like!! Highly recommend this product 100%.
