The truth is that there are some !!!!e Instructors, and there are some really brilliant ones.
I learned to fly with Cabair, and they had a plentiful supply of both variants.
It is (alas) up to the poor, unknowing student to find find for him/herself an instructor who (a) knows their subject, and (b) suits the student.
I spent a lot of money with Cabair before I found an instructor who met both criteria.
(If Cabair's legal team wish to take issue with me, all this is already well documented!)
That said, as a result of spending my money with Cabair, I have (so far) enjoyed over 300 hours of P1 flying which has taken me to Tenerife, Ibetha, US etc.
Caveat Emptor !
