Software was crashing on us at the start so we almost gave up. Thankfully we got to someone from the team over email and they were able to make it work after a week or two with an update. They got us a month for free because of the problem so we are so far quite satisfied with how everything is going. We’re not really following with daily exercises because we just want to improve son’s reading ability (he has hard time reading because he has some problems with convergence).
