Motor car insurance & learner driver

Just got my renewal on My Aviva car insurance Not the same deal as last year with young driver that has passed her module 3 training. It has jumped to €1900 from €950 last year . Has anyone any experience of BoxyMo.ie

Yikes!! Would it make a difference if she passed the driving test?
 
BoxyMo quoted €850 it involves getting a box fitted to monitor her driving and mileage .
I will prob go with that I think
