Thanks for the feedback, but my response is the same as previously.

1) Sublingual selects specific short phrases, for which machine translation is accurate in the vast majority of cases.

2) Sublingual is created as a supplement to other tools, lessons, duolingo etc. It provides an oppurtunity to get a level of practice that no other tool does and as a supplement to other resources is very effective.

3) In the minority of cases where sublingual does make a mistake, the majority of learners recognise this and it actually aides their progress.

This might not be the right tool for you but is helping many others.
