So after reading these posts, I decided to go to Ocean Republic. This was a super choice thanks !
My top priority was to find the cheapest rental. So they do 290 euros for 1 week rental. From all what I searched, I can say that this price is very good. For this price you have brand new gear and very excellent service. The guys there do everything for you ! they setup the kite, launch if if u re beginner, and they pack the kite at the end, even the bar !
From what I heard, other schools at same spot seems to be more oriented on making profitable business.. One guy for example came from another concurrent school Isla, he said the instructor gave him only poor comments and literally just watched him, so he decided to try another school.
Best thing about Ocean republic is the quality of their teaching and the interactions with instructors.
Glen the manager here really takes care of everyone, gives you advises even if u don't take lessons, and is very available and very genuine with the business. The other instructors were good as well. If you rent, you will have advises everyday. I had also a safety rescue lesson in the water teached by english guy, who made it very clear ( some people say that other schools don't like to teach safety rescue because it is unsafe.. ). If u re beginner, renting and struggle to go upwind, instructors did not hesitate to help u take the kite and brings it upwind for u !
The equipment we used for lesson and rental was brand new, slingshot kites rally 2012, and nobile boards, so that part was perfect.
I can only compare with 2 other schools I went in fuerteventura. Red shark and flag beach. Instructors there lacked teaching and communication skills compared to this one. So I can honestly say that Ocean republic rocked with real emphasis on the quality of the teaching.
