Exceptional level of customer support

In July 2016 I purchased three apps: Calculus Made Easy; Physics Made Easy
and Chemistry Made Easy.  These were installed on a ti89 calculator used by
my granddaughter who is a university freshman.  She has reported that the
apps have been very helpful and easy to use.  

I was very impressed by the level of support that Mike provided me.  His responses
were timely; his suggestions and guidance were clear and included step by
step procedures.  

This is an exceptional level of customer support and I
will continue to purchase "Made Easy" products as my granddaughter continues
her education.
