Though it appears to require a very fast internet provider in order to use it properly, I am satisfied and would highly recommend it.

Good experience but unfortunately, I don't need this product at the moment so I will not be renewing my subscription. If I decide to work on taxes in the coming year, I will subscribe.

It works well
It works well, although at times its clunky, but I believe that is due to my pc being too weak to run it smoothly. I would recommend.

I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in. Customer support replies quickly and they are very professional.
