I have been using Brainscapes Chinese flashcard system for over two years until one day it just stopped working. When trying to use it a screen would pop-up with a price structure offering me their features a-la-carte, features I was used. Because of my travel situation it is often difficult for me to access things like the app store and gmail. After sometime I stumbled across an email from Brainscapes owner Mr. Cohen explaining the situation. Personally I did not care for some of the tone of the email about bad reviews he received and him asking users not to "Flame" him in the reviews. He must understand why people are upset when services promised are taken away even accidentally. It is a new business world on the internet and one of the biggest challenges is communication and creating a personal interaction, this is important both in both directions of communication between supplier and customer. That said, I contacted Brainscape as directed using a strongly toned email myself now realizing it was completely unnecessary. In a very short period of time once I provided my receipt (in my mind should not be necessary) they resolved my issue and my Brainscape had its full functionality again. The support staff was responsive and understanding.... Thank you!! I was slightly inconvenienced... my life will go on just fine. THIS PRODUCT IS A FANTASTIC STUDY AID AND I HIGHLY RECOMMEND IT to anybody who is looking for strong additional study material. They have many other offerings that intrigue me and someday if I can carve out a little more time I will purchase another subject even under their new format for product offerings. (businesses must always evolve to stay competitive) At this time however Chinese has proven an exhausting and never ending challenge. My China friends have seen the program and would like to possibly purchase it but I am not sure they can get it off of their app system. I will reach out to Brainscape about this, I know my friends here would like the app in a reverse format. If it is not really offered here Brainscape is missing out on a fairly large consumer population. :) Brainscape deserves the opportunity to satisfy any issues you have before you openly attack them in the market, any business deserves this chance. Cheers and Study in good health. Robert K. -Colorado
