I used the product for close to a month. The idea is brilliant and the support is quick to react.
In my case, the mentor wouldn't respond often. When I asked for my subscription to cancel, it was cancelled immediately (even though I paid for until end of the month) and no refunds were given because "as we've already paid your mentor for the first month". I think mentors lack incentive to perform well.
I am still a fan of the platform and I think with some modification it could become much better.
Creates benefits for both the student and the mentor. The student learns, the mentor gets experience and the feeling of helping someone. It's difficult for many to stay away from their smart-phones... this encourages less brainless app scrolling and more learning.
Benefiting from a mentor experience helps you advance faster.
